Johnson</dc:creator><description>&lt;div&gt;&lt;p&gt;For the last couple of weeks, I have been working on creating a "whiteboard drawing bot", a Raspberry-Pi-powered contraption that can draw shapes and text on a whiteboard. After four redesigns and about a thousand lines of code, I'm finally finished. Tada!&lt;/p&gt;

&lt;/div&gt;

&lt;p&gt;Anyways, now that I have finished building it, I am going to write a bit about how I did so in a few posts. For this first post, I'm going to be talking about the hardware behind the bot and a little bit of the software on the Raspberry Pi. Then, later, I'll talk about the custom software I wrote to translate shapes and lines into commands for the Pi.&lt;/p&gt;
