Arduino 1: TKTracker Simple Light Tracker
A single RC servo and a couple of cheap CdS photoresistors make the Arduino “look alive” by making a simple light tracker. With just a few lines of code you can make the arduino exhibit some lifelike behaviour. I apologize, I thought that I could enter the code in this window but apparently it contains characters that are “illegal”. The program code can be downloaded from www.mediafire.com
