RBG LED Button Matrix 4x4
YouTube via 4mspedals
"This demonstrates a 4x4 button matrix. It's a cross between the Peggy 2 and Sparkfun button board, with my own hack for reading the button presses. An AVR atmega16 controls a STP16DP05 chip and twelve transistors to read the buttons and animate the LEDs. An atmega168 (like in the Arduino) would be suited as well. The matrix can be expanded up to 8x8 without any extra components (just three more button boards and wires running to the motherboard).
There's 8-colors (green, blue, cyan, red, yellow, purple, white, off), but more are possible"
