Hacked this together for a demo at the Boulder Linux Users Group. Had some help from Chris Rojas, Nate Seidle, Ryan Owens, Dave Stillman, and Google. This is the first thing I've built with an Arduino besides blinking a single LED. It is stupid-simple and does not have very many good reasons to exist. Bill of materials: Arduino Duemilanove Servo motor of some sort SparkFun medium-sized shipping box (red) 1 blinky yellow LED Random wires Red electrical tape Chunk of manila folder Orange masking tape Tiny ziptie USB cable loaduino.pde needs to be compiled and loaded to the Arduino. loaduino.pl will run and spit some debugging info if invoked with no options. You may also specify --daemon to run it as a background process. All of this is likely to be a bit flaky.
