Cpsami: /* Final Design */

== Mini bio ==

Hi, I'm Samantha Peterson - I usually go by "sami"

I'm an ICAM (visual) major because an art degree with an emphasis on programming is my idea of a good time. I'm thinking of going into the video gaming industry to become an art director, but I could change my mind at any time. Most of my personal art is in acrylics and mixed media, as well as charcoal drawings. I haven't updated in awhile, but I have a [http://cpsami.deviantart.com deviantart].

=== Useful skills? ===
Following are the skills I have that might help me in this class. Feel free to ask for help.
*programming - Java, Javascript
*HTML, CSS
*Photoshop, Illustrator
*Flash
*painting, drawing

A camera I can actually dissect. It ended up in a cooler overnight and takes ghostly pictures now - when it decides it wants to work, that is.

== Midterm Project ==
'''Pansy Pansy'''

=== Rough Concept ===

I didn't like my other idea. Mostly because I don't want to have to locate a Bible. So, something fun instead: Happy Plant. When you shine a light on it, it jiggles. I'm stealing the parts from a vibrating back massaging device, and trying to learn how to make a photoresistor work...

Rough Visualizations:

http://i1000.photobucket.com/albums/af128/zaydami/for%20school/happyplantcircuit.png

=== Final Design ===

I decided it would be more dynamic if the plant began by shaking, and would only stop when the viewer shines a bright light upon it. The project becomes reinterpreted from a "Happy Plant" that enjoys light, to a "Scaredy Plant" that is afraid of the dark. I think this is thematically more complex and interesting as well. I have always wondered how plants feel about the dark, since they need light to survive. Are they afraid that the sun might not rise again? With a vibrating motor and a photoresistor, I've given the plant the ability to express its fear by shaking in its... roots.

I think people will relate to their own fears of the dark with this project. What would happen if the sun were blocked out by nuclear war? What does it mean if the only emotion the plant can express is fear? (By contrast, does it express relaxation?) And aesthetically, what's the significance of combining something organic with a battery powered mechanical device?

=== Circuit Graphics ===

Here is my circuit design (I think I arranged it correctly):

http://i1000.photobucket.com/albums/af128/zaydami/for%20school/pansycircuit.png

And here is a drawing of how everything is literally linked together:

http://i1000.photobucket.com/albums/af128/zaydami/for%20school/literalcircuit.jpg

I also included a switch that I cannibalized from a toy, and the 1k potentiometer so I can adjust light sensitivity for different light environments.

So, don't leave your plants all alone and scared without a nightlight or something...

== Final Project ==

Working Title: ''The Female Enigma''

=== Rough Concept ===

I want to create a sculpture of a woman with three potentiometers representing her main erogenous zones. The goal would to get people to interact with her body in order to induce "orgasm". There would be some sort of display on my laptop screen which would give feedback. I want to explore woman as analog and how men interact with female bodies digitally. I would construct the sculpture out of clay, and maybe spray it silver.

=== Final Design ===

I decided to do a wire sculpture instead, since it fit thematically with my piece better. I focused less on orgasm and more on the "woman as analog" concept. I have a few thoughts on how the male perspective interacts with female bodies, but I think the piece can have many meanings. The screen displays a woman's body, covered up by pixel-like squares. There are intentional references to pixels to make the piece more about the digitalization of sex.

== Curriculum ==

=== Week 1 - Introduction ===
* Lecture:
** Grading/rules
** Goals
** Art
* Homework 1:
** part 1 - Create a page for yourself on the wiki, adding it to this list [Classes/2010/VIS147A#Student_Pages]. On your personal page, put your name and one paragraph describing your interests in art generally and your interests in electronics and art specifically. Questions to get started: Why are you an art/ICAM major? Are you an art major? Why are you taking this class in particular? Do you have any previous experience with electronics?
** part 2 - Field Research. If it plugs in, has buttons, has a switch, toasts bread, emits light, it probably runs on electricity. We are surrounded by electronic devices. This presents an opportunity. Conceivably, with the right hardware, you can interface with or control any electronic device. Exploring your local environment (your neighborhood, walmart) make a list of electrical devices, and document the 5 most interesting in this regard--things you would like to control. Avoid the dorm room problem--i.e. do not photograph things in your dorm room, apartment, at the price center, etc., unless you have good reason to do so. Dorm room art looks like dorm rooms and thus enters the world severely handicapped. Don't do it!!! Document means photograph, video, or draw. Post images of these five things to the wiki page you made in part 1. If you are feeling extra creative, briefly describe how you would use each item.

* Lecture: Switches, Logic, Loops
* Homework 3: Proposal for Midterm Project: Switches
** Assignment: Build a circuit with a switch. Think creatively about the idea of a switch: you don't have to (and probably shouldn't) use a push button switch from your kit or the knife switch from lab. What could your switch turn on or off? What is a particularly interesting switch (or system) in the world that you would like interface with? What are examples of things that are switched on or off? Mechanical and physical solutions are welcome, although we are of course interested in electrical circuits. This is about the concept of a circuit and the idea of switch interrupting/altering flow--find something to respond to, and be creative in our proposal.
** Due next week in section:
*** 1 paragraph describing
*** 1 visualization of the aesthetic of the piece, how is it going to look?
*** 1 diagram of the function of the piece, how is it going to work?
*** Bring a printed copy to give to your TA for credit, and post it your personal page on the wiki, under "Midterm Project Proposal."
** We will discuss these at the beginning of lecture next week, this is just a first try to get some ideas going. You will be allowed/expected to change your idea before week 5, when the projects are due.

=== Week 6 - POSTPONED ===
I am sorry for the late notice, but...

NOTE: LECTURE IS CANCELED TONIGHT! In lieu of lecture, Steph will be in the electronics lab (VAF 106) from 5-6pm to give a workshop on soldering. If you want to bring your freeduino kit she can help give you finish putting it together.

Great work on your midterms last week, I was very impressed by the thought and effort that went into them!

FYI: Tim and I will be attending the opening of ''and the world is ours...'' at compactspace gallery in LA, from 6-9pm. [http://www.compactspace.com/] All are invited to attend.

Homework for next week: Read pages 1-42 of "Getting Started With Arduino" by Massimo Banzi. This introduces the Arduino microcontroller, a brief bit of what it does, and also describes your first basic activity with the Arduino, writing and uploading the basic LED blinking program.

NOTE: I will use "Arduino" and "Freeduino" interchangeably: they are nearly identical. The official Arduino is manufactured by one particular group in Italy, the Freeduino is one of many clones of the Arduino made by a company here in the US. Both use the same programming environment and have the same capabilities, so we don't really have to worry about the distinction.

=== Week 7 - Microcontrollers, Digital Input/Output ===
* Lecture 7: Introducing the microprocessor.
** Examples from Lecture:
*** blink 3 in a row [[Media:Blink_3inarow.pde | Blink_3inarow.pde]] (right-click to save-as)
*** multiplexer [[Media:Multiplexer.pde | Multiplexer.pde]]
*** push-button multiplexer [[Media:Multiplexer_w_pushbuton.pde | Multiplexer_w_pushbuton.pde]]
*** rate-control knob multiplexer [[Media:Multiplexer_w_rate_control.pde | Multiplexer_w_rate_control.pde]]
* Reference:
** about the Arduino http://arduino.cc/en/Main/ArduinoBoardDuemilanove
** '''duino'''? http://www.freeduino.org/duino.html
** freeduino http://www.freeduino.org/about.html
** freeduino practical reference http://www.freeduino.org/index.html
* Homework 7:
** Familiarize yourself with the following from M.Banzi 'Getting Started With Arduino'. You will be doing much of this in lab next week:
*** Blinking an LED. Banzi p 30-38.
*** Use a Pushbutton To Control a LED. Banzi p 41-45.
*** One circuit, a thousand behaviors. Bazi p. 45-52.
* Arduino in the news: http://www.theatlantic.com/doc/201001/robot-art

=== Week 8 - Analog Input/Output, PWM ===
* Lecture 8:
** Banzi p 56-72.
** Analog Input
** Analog Output, Pulse Width Modulation (PWM).
* Lab 8: [[Classes/2010/VIS147A/Lab8 | analog input/output, PWM]]

=== Week 9 - Interfacing with the computer, higher level sensors ===
* Lecture:
** serial communication
* Homework 9:
* Lab 9: [[Classes/2010/VIS147A/Lab9 | serial communication]]

==== Problems with lab 9 ====

(Christa & Samantha were working on the rudimentary keyboard control for processing and this is what they came up with. Can anyone fix the code? The problem seems to lie within the port.write() function. The code given in lab doesn't work because it is actually code for Arduino, not Processing)

/* Processing code for this example */
// Dimmer - sends bytes over a serial port
// by David A. Mellis

// This example code is in the public domain.
import processing.serial.*;
Serial port;
int value;

void setup() {
size(256, 150);

println("Available serial ports:");
println(Serial.list());

// Uses the first port in this list (number 0). Change this to
// select the port corresponding to your Arduino board. The last
// parameter (e.g. 9600) is the speed of the communication. It
// has to correspond to the value passed to Serial.begin() in your
// Arduino sketch.
port = new Serial(this, Serial.list()[0], 9600);

// If you know the name of the port used by the Arduino board, you
// can specify it directly like this.
//port = new Serial(this, "COM1", 9600);
}

void draw(){
port.write(value*28);
}

void keyReleased() {
if (key >= '0' && key <= '9') {
value = key - '0';
// port.write(value*28);
println(key);
println(value);

}

}

=== Week 10 - Summary, discussion, wind-down. ===
* Lecture:
* Homework 10: work on finals. get help
* For Next Week: finish final projects

=== Final Project ===
Assignment:

The final project is an open assignment similar to the midterm in that you need to identify and articulate an interest / something you want to make. This time, however, you need to use the Arduino for the project and both the code and the hardware will be considered in your grade. The Arduino presents you with new opportunities, to create:
* A networked object, which either takes data in off of the computer, or sends it out into the world. see [http://books.google.com/books?id=K0nLbhWrTukC&dq=making+things+talk&printsec=frontcover&source=bn&hl=en&ei=QzeNS6LVO4H6sgPfqIytAw&sa=X&oi=book_result&ct=result&resnum=4&ved=0CBsQ6AEwAw#v=onepage&q=&f=false Making Things Talk, Tom Igoe]
* An object with multiple inputs, multiple outputs, or complex relationships between inputs and outputs.
* Think of some of the sensors I have shown in class (and others I have mentioned): do you want to make a project with a 3 axis accelerometer, which is sensitive to position? Do you want to use a range finder? Do a little digging on the possibilities and think ahead on this, so you can order a sensor online if you need to.

If you are looking for inspiration, snoop around the Arduino playground http://www.arduino.cc/playground/, particularly the gallery of previous projects [http://www.arduino.cc/playground/Projects/ArduinoUsers]. Also look on http://instructables.com, http://makezine.com, and many others. Google searches are good.

Format:
* Proposal, posted on your wiki page in a new ''Final Project'' section:
** Two paragraph written description of your idea.
** One (or more) diagrams of the function of your project.
** One (or more) illustration of the appearance of the project. You can include additional reference imagery that is relevant to your project. Whatever helps convey the idea you are going for.
* Realization / Presentation in class.
** For this project try to avoid showing us exposed breadboards. Solder things up. Hide your circuitry away cleverly. Wow us with your techno-wizardry.
* Documentation, posted on your wiki page in a new ''Final Project Documentation'' section:
** 5 images/videos of your project as completed. Take these as if they belong in your art portfolio (b.c. they do!)--i.e. try to take them with good lighting, against a white background, with no other distractions in frame. We do not want to see dorm room carpets. Good photographic documentation will focus on the art object and nothing else!
** Post the source code for your final project on the wiki. Comment it so your fellow classmates can understand what you have done. And be sure to put your name at the top!

== Curriculum ==

=== Week 1 - Introduction ===
* Lecture:
** Grading/rules
** Goals
** Art
* Homework 1:
** part 1 - Create a page for yourself on the wiki, adding it to this list [Classes/2010/VIS147A#Student_Pages]. On your personal page, put your name and one paragraph describing your interests in art generally and your interests in electronics and art specifically. Questions to get started: Why are you an art/ICAM major? Are you an art major? Why are you taking this class in particular? Do you have any previous experience with electronics?
** part 2 - Field Research. If it plugs in, has buttons, has a switch, toasts bread, emits light, it probably runs on electricity. We are surrounded by electronic devices. This presents an opportunity. Conceivably, with the right hardware, you can interface with or control any electronic device. Exploring your local environment (your neighborhood, walmart) make a list of electrical devices, and document the 5 most interesting in this regard--things you would like to control. Avoid the dorm room problem--i.e. do not photograph things in your dorm room, apartment, at the price center, etc., unless you have good reason to do so. Dorm room art looks like dorm rooms and thus enters the world severely handicapped. Don't do it!!! Document means photograph, video, or draw. Post images of these five things to the wiki page you made in part 1. If you are feeling extra creative, briefly describe how you would use each item.

* Lecture: Switches, Logic, Loops
* Homework 3: Proposal for Midterm Project: Switches
** Assignment: Build a circuit with a switch. Think creatively about the idea of a switch: you don't have to (and probably shouldn't) use a push button switch from your kit or the knife switch from lab. What could your switch turn on or off? What is a particularly interesting switch (or system) in the world that you would like interface with? What are examples of things that are switched on or off? Mechanical and physical solutions are welcome, although we are of course interested in electrical circuits. This is about the concept of a circuit and the idea of switch interrupting/altering flow--find something to respond to, and be creative in our proposal.
** Due next week in section:
*** 1 paragraph describing
*** 1 visualization of the aesthetic of the piece, how is it going to look?
*** 1 diagram of the function of the piece, how is it going to work?
*** Bring a printed copy to give to your TA for credit, and post it your personal page on the wiki, under "Midterm Project Proposal."
** We will discuss these at the beginning of lecture next week, this is just a first try to get some ideas going. You will be allowed/expected to change your idea before week 5, when the projects are due.

* Lab 5: [[Classes/2010/VIS147A/Lab6 | Build your Arduino!]]

=== Week 6 - POSTPONED ===
I am sorry for the late notice, but...

NOTE: LECTURE IS CANCELED TONIGHT! In lieu of lecture, Steph will be in the electronics lab (VAF 106) from 5-6pm to give a workshop on soldering. If you want to bring your freeduino kit she can help give you finish putting it together.

Great work on your midterms last week, I was very impressed by the thought and effort that went into them!

FYI: Tim and I will be attending the opening of ''and the world is ours...'' at compactspace gallery in LA, from 6-9pm. [http://www.compactspace.com/] All are invited to attend.

Homework for next week: Read pages 1-42 of "Getting Started With Arduino" by Massimo Banzi. This introduces the Arduino microcontroller, a brief bit of what it does, and also describes your first basic activity with the Arduino, writing and uploading the basic LED blinking program.

NOTE: I will use "Arduino" and "Freeduino" interchangeably: they are nearly identical. The official Arduino is manufactured by one particular group in Italy, the Freeduino is one of many clones of the Arduino made by a company here in the US. Both use the same programming environment and have the same capabilities, so we don't really have to worry about the distinction.

=== Week 7 - Microcontrollers, Digital Input/Output ===
* Lecture 7: Introducing the microprocessor.
** Examples from Lecture:
*** blink 3 in a row [[Media:Blink_3inarow.pde | Blink_3inarow.pde]] (right-click to save-as)
*** multiplexer [[Media:Multiplexer.pde | Multiplexer.pde]]
*** push-button multiplexer [[Media:Multiplexer_w_pushbuton.pde | Multiplexer_w_pushbuton.pde]]
*** rate-control knob multiplexer [[Media:Multiplexer_w_rate_control.pde | Multiplexer_w_rate_control.pde]]
* Reference:
** about the Arduino http://arduino.cc/en/Main/ArduinoBoardDuemilanove
** '''duino'''? http://www.freeduino.org/duino.html
** freeduino http://www.freeduino.org/about.html
** freeduino practical reference http://www.freeduino.org/index.html
* Homework 7:
** Familiarize yourself with the following from M.Banzi 'Getting Started With Arduino'. You will be doing much of this in lab next week:
*** Blinking an LED. Banzi p 30-38.
*** Use a Pushbutton To Control a LED. Banzi p 41-45.
*** One circuit, a thousand behaviors. Bazi p. 45-52.
* Arduino in the news: http://www.theatlantic.com/doc/201001/robot-art
* OPTIONAL: Call for works [http://blog.makezine.com/archive/2010/02/one-button_objects_-_call_for_works.html One Button Objects] deadline March 1.
* Lab 7: [[Classes/2010/VIS147A/Lab7 | Digital Input/Output]]

=== Week 8 - Analog Input/Output, PWM ===
* Lecture 8:
** Banzi p 56-72.
** Analog Input
** Analog Output, Pulse Width Modulation (PWM).
* Lab 8: [[Classes/2010/VIS147A/Lab8 | analog input/output, PWM]]
* Homework 8: Proposals for final projects. Finish lab exercises.
[[Classes/2010/VIS147A#Final_Project | Final project assignment]]

=== Week 9 - Interfacing with the computer, higher level sensors ===
* Lecture:
** serial communication
* Homework 9:
* Lab 9: [[Classes/2010/VIS147A/Lab9 | serial communication]]

==== Problems with lab 9 ===

(Christa & Samantha were working on the rudimentary keyboard control for processing and this is what they came up with. Can anyone fix the code? The problem seems to lie within the port.write() function. The code given in lab doesn't work because it is actually code for Arduino, not Processing)

/* Processing code for this example */
// Dimmer - sends bytes over a serial port
// by David A. Mellis

// This example code is in the public domain.
import processing.serial.*;
Serial port;
int value;

void setup() {
size(256, 150);

println("Available serial ports:");
println(Serial.list());

// Uses the first port in this list (number 0). Change this to
// select the port corresponding to your Arduino board. The last
// parameter (e.g. 9600) is the speed of the communication. It
// has to correspond to the value passed to Serial.begin() in your
// Arduino sketch.
port = new Serial(this, Serial.list()[0], 9600);

// If you know the name of the port used by the Arduino board, you
// can specify it directly like this.
//port = new Serial(this, "COM1", 9600);
}

void draw(){
port.write(value*28);
}

void keyReleased() {
if (key >= '0' && key <= '9') {
value = key - '0';
// port.write(value*28);
println(key);
println(value);

}

}

=== Week 10 - Summary, discussion, wind-down. ===
* Lecture:
* Homework 10: work on finals. get help
* For Next Week: finish final projects

=== Final Project ===
Assignment:

The final project is an open assignment similar to the midterm in that you need to identify and articulate an interest / something you want to make. This time, however, you need to use the Arduino for the project and both the code and the hardware will be considered in your grade. The Arduino presents you with new opportunities, to create:
* A networked object, which either takes data in off of the computer, or sends it out into the world. see [http://books.google.com/books?id=K0nLbhWrTukC&dq=making+things+talk&printsec=frontcover&source=bn&hl=en&ei=QzeNS6LVO4H6sgPfqIytAw&sa=X&oi=book_result&ct=result&resnum=4&ved=0CBsQ6AEwAw#v=onepage&q=&f=false Making Things Talk, Tom Igoe]
* An object with multiple inputs, multiple outputs, or complex relationships between inputs and outputs.
* Think of some of the sensors I have shown in class (and others I have mentioned): do you want to make a project with a 3 axis accelerometer, which is sensitive to position? Do you want to use a range finder? Do a little digging on the possibilities and think ahead on this, so you can order a sensor online if you need to.

If you are looking for inspiration, snoop around the Arduino playground http://www.arduino.cc/playground/, particularly the gallery of previous projects [http://www.arduino.cc/playground/Projects/ArduinoUsers]. Also look on http://instructables.com, http://makezine.com, and many others. Google searches are good.

Format:
* Proposal, posted on your wiki page in a new ''Final Project'' section:
** Two paragraph written description of your idea.
** One (or more) diagrams of the function of your project.
** One (or more) illustration of the appearance of the project. You can include additional reference imagery that is relevant to your project. Whatever helps convey the idea you are going for.
* Realization / Presentation in class.
** For this project try to avoid showing us exposed breadboards. Solder things up. Hide your circuitry away cleverly. Wow us with your techno-wizardry.
* Documentation, posted on your wiki page in a new ''Final Project Documentation'' section:
** 5 images/videos of your project as completed. Take these as if they belong in your art portfolio (b.c. they do!)--i.e. try to take them with good lighting, against a white background, with no other distractions in frame. We do not want to see dorm room carpets. Good photographic documentation will focus on the art object and nothing else!
** Post the source code for your final project on the wiki. Comment it so your fellow classmates can understand what you have done. And be sure to put your name at the top!

== Grading ==
Overall grade:
* Assignments 50%
* Midterm Project 20%
* Final Project 30%

Assignments are graded on completion. If I assign something during lecture or if you do not finish a lab activity, that item will be due by the next section (one week later). If you finish on time, you will get 100% credit.

Attendance is mandatory. Each absence (from lecture or section) is a 1/2 letter grade deduction off your final grade. Three absences is a failing grade.

Projects are graded on :
* 33.3% - concept/proposal
* 33.3% - effort
* 33.3% - realization/documentation

Readings will familiarize you with material covered in lecture.

=== Week 1 - Introduction ===
* Lecture:
** Grading/rules
** Goals
** Art
* Homework 1:
** part 1 - Create a page for yourself on the wiki, adding it to this list [Classes/2010/VIS147A#Student_Pages]. On your personal page, put your name and one paragraph describing your interests in art generally and your interests in electronics and art specifically. Questions to get started: Why are you an art/ICAM major? Are you an art major? Why are you taking this class in particular? Do you have any previous experience with electronics?
** part 2 - Field Research. If it plugs in, has buttons, has a switch, toasts bread, emits light, it probably runs on electricity. We are surrounded by electronic devices. This presents an opportunity. Conceivably, with the right hardware, you can interface with or control any electronic device. Exploring your local environment (your neighborhood, walmart) make a list of electrical devices, and document the 5 most interesting in this regard--things you would like to control. Avoid the dorm room problem--i.e. do not photograph things in your dorm room, apartment, at the price center, etc., unless you have good reason to do so. Dorm room art looks like dorm rooms and thus enters the world severely handicapped. Don't do it!!! Document means photograph, video, or draw. Post images of these five things to the wiki page you made in part 1. If you are feeling extra creative, briefly describe how you would use each item.

* Lecture: Switches, Logic, Loops
* Homework 3: Proposal for Midterm Project: Switches
** Assignment: Build a circuit with a switch. Think creatively about the idea of a switch: you don't have to (and probably shouldn't) use a push button switch from your kit or the knife switch from lab. What could your switch turn on or off? What is a particularly interesting switch (or system) in the world that you would like interface with? What are examples of things that are switched on or off? Mechanical and physical solutions are welcome, although we are of course interested in electrical circuits. This is about the concept of a circuit and the idea of switch interrupting/altering flow--find something to respond to, and be creative in our proposal.
** Due next week in section:
*** 1 paragraph describing
*** 1 visualization of the aesthetic of the piece, how is it going to look?
*** 1 diagram of the function of the piece, how is it going to work?
*** Bring a printed copy to give to your TA for credit, and post it your personal page on the wiki, under "Midterm Project Proposal."
** We will discuss these at the beginning of lecture next week, this is just a first try to get some ideas going. You will be allowed/expected to change your idea before week 5, when the projects are due.

=== Week 6 - POSTPONED ===
I am sorry for the late notice, but...

NOTE: LECTURE IS CANCELED TONIGHT! In lieu of lecture, Steph will be in the electronics lab (VAF 106) from 5-6pm to give a workshop on soldering. If you want to bring your freeduino kit she can help give you finish putting it together.

Great work on your midterms last week, I was very impressed by the thought and effort that went into them!

FYI: Tim and I will be attending the opening of ''and the world is ours...'' at compactspace gallery in LA, from 6-9pm. [http://www.compactspace.com/] All are invited to attend.

Homework for next week: Read pages 1-42 of "Getting Started With Arduino" by Massimo Banzi. This introduces the Arduino microcontroller, a brief bit of what it does, and also describes your first basic activity with the Arduino, writing and uploading the basic LED blinking program.

NOTE: I will use "Arduino" and "Freeduino" interchangeably: they are nearly identical. The official Arduino is manufactured by one particular group in Italy, the Freeduino is one of many clones of the Arduino made by a company here in the US. Both use the same programming environment and have the same capabilities, so we don't really have to worry about the distinction.

=== Week 7 - Microcontrollers, Digital Input/Output ===
* Lecture 7: Introducing the microprocessor.
** Examples from Lecture:
*** blink 3 in a row [[Media:Blink_3inarow.pde | Blink_3inarow.pde]] (right-click to save-as)
*** multiplexer [[Media:Multiplexer.pde | Multiplexer.pde]]
*** push-button multiplexer [[Media:Multiplexer_w_pushbuton.pde | Multiplexer_w_pushbuton.pde]]
*** rate-control knob multiplexer [[Media:Multiplexer_w_rate_control.pde | Multiplexer_w_rate_control.pde]]
* Reference:
** about the Arduino http://arduino.cc/en/Main/ArduinoBoardDuemilanove
** '''duino'''? http://www.freeduino.org/duino.html
** freeduino http://www.freeduino.org/about.html
** freeduino practical reference http://www.freeduino.org/index.html
* Homework 7:
** Familiarize yourself with the following from M.Banzi 'Getting Started With Arduino'. You will be doing much of this in lab next week:
*** Blinking an LED. Banzi p 30-38.
*** Use a Pushbutton To Control a LED. Banzi p 41-45.
*** One circuit, a thousand behaviors. Bazi p. 45-52.

=== Week 9 - Interfacing with the computer, higher level sensors ===
* Lecture:
** serial communication
* Homework 9:
* Lab 9: [[Classes/2010/VIS147A/Lab9 | serial communication]]

==== Problems with lab 9 ===

(Christa & Samantha were working on the rudimentary keyboard control for processing and this is what they came up with. Can anyone fix the code? The problem seems to lie within the port.write() function. The code given in lab doesn't work because it is actually code for Arduino, not Processing)

/* Processing code for this example */
// Dimmer - sends bytes over a serial port
// by David A. Mellis

// This example code is in the public domain.
import processing.serial.*;
Serial port;
int value;

void setup() {
size(256, 150);

println("Available serial ports:");
println(Serial.list());

// Uses the first port in this list (number 0). Change this to
// select the port corresponding to your Arduino board. The last
// parameter (e.g. 9600) is the speed of the communication. It
// has to correspond to the value passed to Serial.begin() in your
// Arduino sketch.
port = new Serial(this, Serial.list()[0], 9600);

// If you know the name of the port used by the Arduino board, you
// can specify it directly like this.
//port = new Serial(this, "COM1", 9600);
}

void draw(){
port.write(value);
}

void keyReleased() {
if (key >= '0' && key <= '9') {
value = key - '0';
// port.write(value*28);
println(key);
println(value);

}

}

=== Week 10 - Summary, discussion, wind-down. ===
* Lecture:
* Homework 10: work on finals. get help
* For Next Week: finish final projects

=== Final Project ===
Assignment:

The final project is an open assignment similar to the midterm in that you need to identify and articulate an interest / something you want to make. This time, however, you need to use the Arduino for the project and both the code and the hardware will be considered in your grade. The Arduino presents you with new opportunities, to create:
* A networked object, which either takes data in off of the computer, or sends it out into the world. see [http://books.google.com/books?id=K0nLbhWrTukC&dq=making+things+talk&printsec=frontcover&source=bn&hl=en&ei=QzeNS6LVO4H6sgPfqIytAw&sa=X&oi=book_result&ct=result&resnum=4&ved=0CBsQ6AEwAw#v=onepage&q=&f=false Making Things Talk, Tom Igoe]
* An object with multiple inputs, multiple outputs, or complex relationships between inputs and outputs.
* Think of some of the sensors I have shown in class (and others I have mentioned): do you want to make a project with a 3 axis accelerometer, which is sensitive to position? Do you want to use a range finder? Do a little digging on the possibilities and think ahead on this, so you can order a sensor online if you need to.

If you are looking for inspiration, snoop around the Arduino playground http://www.arduino.cc/playground/, particularly the gallery of previous projects [http://www.arduino.cc/playground/Projects/ArduinoUsers]. Also look on http://instructables.com, http://makezine.com, and many others. Google searches are good.

Format:
* Proposal, posted on your wiki page in a new ''Final Project'' section:
** Two paragraph written description of your idea.
** One (or more) diagrams of the function of your project.
** One (or more) illustration of the appearance of the project. You can include additional reference imagery that is relevant to your project. Whatever helps convey the idea you are going for.
* Realization / Presentation in class.
** For this project try to avoid showing us exposed breadboards. Solder things up. Hide your circuitry away cleverly. Wow us with your techno-wizardry.
* Documentation, posted on your wiki page in a new ''Final Project Documentation'' section:
** 5 images/videos of your project as completed. Take these as if they belong in your art portfolio (b.c. they do!)--i.e. try to take them with good lighting, against a white background, with no other distractions in frame. We do not want to see dorm room carpets. Good photographic documentation will focus on the art object and nothing else!
** Post the source code for your final project on the wiki. Comment it so your fellow classmates can understand what you have done. And be sure to put your name at the top!

== Mini bio ==

Hi, I'm Samantha Peterson - I usually go by "sami"

I'm an ICAM (visual) major because an art degree with an emphasis on programming is my idea of a good time. I'm thinking of going into the video gaming industry to become an art director, but I could change my mind at any time. Most of my personal art is in acrylics and mixed media, as well as charcoal drawings. I haven't updated in awhile, but I have a [http://cpsami.deviantart.com deviantart].

*HTML, CSS
*Photoshop, Illustrator
*Flash
*painting, drawing
*various crafts (jewelry, plastic bag fusing, making chocolate truffles?...)

A camera I can actually dissect. It ended up in a cooler overnight and takes ghostly pictures now - when it decides it wants to work, that is.

== Midterm Project ==
'''Pansy Pansy'''

=== Rough Concept ===

I didn't like my other idea. Mostly because I don't want to have to locate a Bible. So, something fun instead: Happy Plant. When you shine a light on it, it jiggles. I'm stealing the parts from a vibrating back massaging device, and trying to learn how to make a photoresistor work...

Rough Visualizations:

http://i1000.photobucket.com/albums/af128/zaydami/for%20school/happyplant.png

http://i1000.photobucket.com/albums/af128/zaydami/for%20school/happyplantcircuit.png

=== Final Design ===

I decided it would be more dynamic if the plant began by shaking, and would only stop when the viewer shines a bright light upon it. The project becomes reinterpreted from a "Happy Plant" that enjoys light, to a "Scaredy Plant" that is afraid of the dark. I think this is thematically more complex and interesting as well. I have always wondered how plants feel about the dark, since they need light to survive. Are they afraid that the sun might not rise again? With a vibrating motor and a photoresistor, I've given the plant the ability to express its fear by shaking in its... roots.

I think people will relate to their own fears of the dark with this project. What would happen if the sun were blocked out by nuclear war? What does it mean if the only emotion the plant can express is fear? (By contrast, does it express relaxation?) And aesthetically, what's the significance of combining something organic with a battery powered mechanical device?

=== Circuit Graphics ===

Here is my circuit design (I think I arranged it correctly):

http://i1000.photobucket.com/albums/af128/zaydami/for%20school/pansycircuit.png

And here is a drawing of how everything is literally linked together:

http://i1000.photobucket.com/albums/af128/zaydami/for%20school/literalcircuit.jpg

I also included a switch that I cannibalized from a toy, and the 1k potentiometer so I can adjust light sensitivity for different light environments.

=== Photo Documentation ===

A perfectly still, calm Purple Pansy in the light:

A frightened flower in the dark:
(DRAMATIZATION)

http://i1000.photobucket.com/albums/af128/zaydami/for%20school/fraidypansy.png

So, don't leave your plants all alone and scared without a nightlight or something...

== Final Project ==

Working Title: ''The Doppelganger''

=== Rough Concept ===

I will use either a motion sensor or a microphone to detect when viewers are in front of my device. This will either cause a mirror to light up or for the device to project an image (camera obscura style perhaps) of the viewer and it will be somehow altered. I want to explore the way we have alternate personas and how complex they can become. Can I make some viewers realize just how "two-faced" they can be? What is it like to have multiple-personality disorder?

Hi, I'm Samantha Peterson - I usually go by "sami"

I'm an ICAM (visual) major because an art degree with an emphasis on programming is my idea of a good time. I'm thinking of going into the video gaming industry to become an art director, but I could change my mind at any time.

Following are the skills I have that might help me in this class. Feel free to ask for help.

*HTML, CSS
*Photoshop, Illustrator
*Flash
*painting, drawing

*sewing
