Spark Fun electronics has a new RGB controller for LEDS – “The RGB Matrix Controller is a small backpack that attaches to an Red/Green/Blue LED matrix and allows control over simple serial SPI communication. This allieviates the end user from having to do the individual LED scanning and refreshing. 7 different colors are possible on any of the 64 LEDs in the array. You can even reprogram the on board ATMega8 to monitor external sensors and switches! Also available in a Red/Green configuration.” – Link.
