&lt;div&gt;== FIREFLY ==&lt;br /&gt;
&lt;br /&gt;
For my final project,, I would like to create a ball of LED&amp;#039;s encased in a clear or colored bouncy ball that not only changes color but acts as if fireflies are inside.  In order to create this, I plan on drawing from the idea of &amp;quot;Charlieplexing&amp;quot; and driving multiple LED&amp;#039;s with the limited number of inputs on the Arduino board.  The end result would not only be an exploration of how to wire multiple LED&amp;#039;s that function together like a bouncing particle but also an aesthetic venture in deconstructing the monotony of static bouncy balls.&lt;br /&gt;

&lt;br /&gt;
* Introduction&lt;br /&gt;
* Assemble your Freeduino: &lt;br /&gt;
** INSTRUCTIONS: http://mcukits.com/2009/03/12/assembling-the-freeduino-board-kit/&lt;br /&gt;

* Assignment: Assembled, functioning Freeduino, communicating with computer, able to upload test sketches, before next class.&lt;br /&gt;
* NOTE: We have a newer, beefier processor than the original Arduino.  You need to tell the Arduino software this. &lt;br /&gt;
** (if you had problems uploading, this may have been why)&lt;br /&gt;
**In the Arduino software, under Tools-&amp;gt;Board, select the Duemilanove w/ Atmega 328.&lt;br /&gt;

** to make a 3d scanner http://hackedgadgets.com/2009/04/02/3d-arduino-scanner/&lt;br /&gt;
** with 2 servos (to be demonstrated), and an IR range-finder: http://www.acroname.com/robotics/parts/R144-GP2Y0A02YK.html&lt;br /&gt;
* Have you seen anything you like?&lt;br /&gt;

=== Week 3 - PWM, Analog Input/Output ===&lt;br /&gt;
* lights, fading&lt;br /&gt;
* sounds, tone generation&lt;br /&gt;
* Basic motor control (DC motors) see week 5&lt;br /&gt;

&lt;br /&gt;
=== Week 5 - Catchup / Oscilloscope / Your own projects ===&lt;br /&gt;
* Discuss homework. &lt;br /&gt;
* The Oscilloscope (Ah-ha!)&lt;br /&gt;
* Wikis (take it away Chris) &lt;br /&gt;
* HOMEWORK: Look on-line to find an interesting project someone has made with an Arduino.  Register for this Wiki (instructions below), and post a link to the project you found, along with a short paragraph describing your interest in the project. PLEASE WRITE A PARAGRAPH describing your interest in the project, what aspects are relevant to your own possible final project, etc.  &lt;br /&gt;

=== Main Board ===&lt;br /&gt;
&lt;br /&gt;
Many different options.  All share a common programming environment, common code, and a similar physical layout.   The board we are using does not require an external USB adaptor, which means all we need to do to program (and power) it is to plug it into the computer with a USB cable. &lt;br /&gt;
