The Arduino-Based Dual Relay Control Board

This project allows us to use an Arduino to control any AC powered device, including lamps and small heaters.  Its limited to 20A, but a lot can be done with 20A.  The picture below shows it running two 12V PC case fans. The arduino Uno controlling this device is located underneath the board (out of view in the picture).
