[[Image: truck_500px.jpg]]   Midterm Project: For my midterm project, I installed a speaker box that tells a narrative based on the song “Mary Had A Little Lamb” in a jacket. I removed the apparatus from a book with a little stuffed lamb that read the story aloud. Originally, a magnet embedded in one of the lamb’s feet was used to close the circuit, which was embedded in another foot, and ultimately trigger the speaker. I simply cut both of the wires, removing the magnetic component, and attached one wire to each half of the button enclosure on the front pocket of the jacket. . So, when the pocket is closed, the circuit is closed also, prompting the speaker to tell the story. In hindsight, I could have kept the magnetic component, attaching it to one half of the button, but alas, this occurred to me all too late. The jacket, appropriately, is lined with a material that simulates sheepskin. If possible, I would have preferred to use a piece of clothing that incorporated actual sheepskin, or wool. Ideally, I would have loved to use a pair of Ugg boots. Unfortunately I do not own any such items. Aesthetically, however, I feel that this jacket makes the proper point. It puts a new spin on the words, “Mary had a little lamb, whose fleece was white as snow. And everywhere that Mary went, the lamb was sure to go.”  [[Image: Midterm circuit2.jpg]] [[Image: Midterm jacket.jpg]] [[Image: Midterm wiring1.jpg]] [[Image: Midterm wiring2.jpg]]     Final Project Proposal In lieu of the recent budget cuts, I would like to comment on the rising cost of education. To do this, I would like to install a speaker in a textbook that will emit an S.O.S. signal, signifying the distress that public education is currently in. This will require wiring up a speaker to one of the digital out pins on the Arduino. Musical notes can be specified with code. I will hollow out a portion of the inside of the textbook to house the electronic components and somehow install a switch on the outside of the book to trigger the sound.  Final Project Write-Up In lieu of the recent budget cuts and increase in tuition costs, I've decided to comment on the current peril of public higher education. I've installed a speaker in a textbook and programmed my Arduino to perform an S.O.S. signal a number of times, which turns into the sound of a cardiac monitor, followed by a simple rendition of the Funeral March.  [[Image: Book.jpg]] [[Image: Bookswitch.jpg]] [[Image: Openbook.jpg]] [[Image: Bookpage.jpg]] The Circuit: [[Image: CIRCUIT_500A.jpg]] The Code:  #include "pitches.h"  // notes int SOS[] = { NOTE_A4,NOTE_A4,NOTE_A4,NOTE_A4,NOTE_A4,NOTE_A4,NOTE_A4,NOTE_A4,NOTE_A4,NOTE_0 }; // note durations: 4 = quarter note, 8 = eighth note, etc.: int toneDurations[] = { 4,4,4,2,2,2,4,4,4,4 }; int cardiacBeep[] = { NOTE_A4,NOTE_A4,NOTE_A4,NOTE_A4,NOTE_A4 }; int cardiacBeepDurations[] = { 4,4,4,4,4 };  int melody[] = { NOTE_A4,NOTE_A4,NOTE_A4,NOTE_A4,NOTE_C5,NOTE_B4,NOTE_B4,NOTE_A4,NOTE_A4,NOTE_A4,NOTE_A4};  int noteDurations[] = { 2, 2, 4, 1,2,4,2,4,2,4,1 };  void setup() { //run SOS 3 times for (int runSOS = 0; runSOS < 3; runSOS++) { // SOS for (int thisTone = 0; thisTone < 10; thisTone++) { // to calculate the tone duration, take one second, divided by note type int toneDuration = 1000/toneDurations[thisTone]; // call tone tone(8,SOS[thisTone],toneDuration); // silence to distinguish between notes int pauseBetweenTones = toneDuration*2; delay(pauseBetweenTones); } } // begin cardiac beep for (int thisCardiacBeep = 0; thisCardiacBeep < 5; thisCardiacBeep++) { int cardiacBeepDuration = 1000/cardiacBeepDurations[thisCardiacBeep]; tone(8,cardiacBeep[thisCardiacBeep],cardiacBeepDuration); int pauseBetweenBeeps = cardiacBeepDuration*5.3; delay(pauseBetweenBeeps); } // cardiac arrest tone(8,NOTE_A4,5000); // pause before funeral march delay(6000); // begin Funeral March for (int thisNote = 0; thisNote < 11; thisNote++) {  int noteDuration = 1000/noteDurations[thisNote]; tone(8,melody[thisNote],noteDuration); int pauseBetweenNotes = noteDuration*1.1; delay(pauseBetweenNotes); } }  void loop() { // no need to repeat the melody. } Include this on a second tab within the Arduino sketch:  #define NOTE_0 0 #define NOTE_B0 31 #define NOTE_C1 33 #define NOTE_CS1 35 #define NOTE_D1 37 #define NOTE_DS1 39 #define NOTE_E1 41 #define NOTE_F1 44 #define NOTE_FS1 46 #define NOTE_G1 49 #define NOTE_GS1 52 #define NOTE_A1 55 #define NOTE_AS1 58 #define NOTE_B1 62 #define NOTE_C2 65 #define NOTE_CS2 69 #define NOTE_D2 73 #define NOTE_DS2 78 #define NOTE_E2 82 #define NOTE_F2 87 #define NOTE_FS2 93 #define NOTE_G2 98 #define NOTE_GS2 104 #define NOTE_A2 110 #define NOTE_AS2 117 #define NOTE_B2 123 #define NOTE_C3 131 #define NOTE_CS3 139 #define NOTE_D3 147 #define NOTE_DS3 156 #define NOTE_E3 165 #define NOTE_F3 175 #define NOTE_FS3 185 #define NOTE_G3 196 #define NOTE_GS3 208 #define NOTE_A3 220 #define NOTE_AS3 233 #define NOTE_B3 247 #define NOTE_C4 262 #define NOTE_CS4 277 #define NOTE_D4 294 #define NOTE_DS4 311 #define NOTE_E4 330 #define NOTE_F4 349 #define NOTE_FS4 370 #define NOTE_G4 392 #define NOTE_GS4 415 #define NOTE_A4 440 #define NOTE_AS4 466 #define NOTE_B4 494 #define NOTE_C5 523 #define NOTE_CS5 554 #define NOTE_D5 587 #define NOTE_DS5 622 #define NOTE_E5 659 #define NOTE_F5 698 #define NOTE_FS5 740 #define NOTE_G5 784 #define NOTE_GS5 831 #define NOTE_A5 880 #define NOTE_AS5 932 #define NOTE_B5 988 #define NOTE_C6 1047 #define NOTE_CS6 1109 #define NOTE_D6 1175 #define NOTE_DS6 1245 #define NOTE_E6 1319 #define NOTE_F6 1397 #define NOTE_FS6 1480 #define NOTE_G6 1568 #define NOTE_GS6 1661 #define NOTE_A6 1760 #define NOTE_AS6 1865 #define NOTE_B6 1976 #define NOTE_C7 2093 #define NOTE_CS7 2217 #define NOTE_D7 2349 #define NOTE_DS7 2489 #define NOTE_E7 2637 #define NOTE_F7 2794 #define NOTE_FS7 2960 #define NOTE_G7 3136 #define NOTE_GS7 3322 #define NOTE_A7 3520 #define NOTE_AS7 3729 #define NOTE_B7 3951 #define NOTE_C8 4186 #define NOTE_CS8 4435 #define NOTE_D8 4699 #define NOTE_DS8 4978   When I first wired the speaker up with the Arduino and the breadboard, the signal was very weak and produced a very quiet tone. I decided to add the TIP120 and the diode to increase the volume of the signal. I wanted to make the piece self-contained and not require a laptop for power, so I powered the Arduino with a 9V battery. In doing so, I discovered that my DC in on my Arduino didn't work, so I clipped a micro USB plug from and old cell phone charger and soldered it to the wires from the battery. I then cut out a section of a textbook to house the electronics. Finally, I added a push-to-break switch so that the program could be triggered without having to open the book. The switch shuts the Arduino off momentarily, causing it to restart the program.
