Arduino Micro Controller for the Lights

The Arduino can be used for many things when It comes to R2.  The lights is a good reason to use one, as it makes them flash and do all sorts of interesting things.  I have the Arduino Pro Mini and it only cost about $10.  This is extremely inexpensive for something that does so much for our little droid.
