A LED shield for an Arduino Uno that uses three daisy chained TLC5940s to control 16 RGB LEDS with PWM functionality. It can act mainly as a nightlight, but one in which you can program your own patterns (and give to your friends)! I used the wonderful TLC5940 Arduino library to control the chips. Code is free software, and the board files are available from the link below. You should be able to pop the zip right into OSH Park.
