Small 8X8 LED Array based on ATmega16

This small 8X8 LED array packs a ton of smarts in a small package. The code for the ATmega16 is available as well as the Eagle PCB layout.

Thanks Martin

"ATmega16 is powered from two CR2016 lithium cells. AVR is using internal RC oscillator @8MHz. The supply voltage is 6.0V. Lower voltages works too, but the image isn’t so bright, especially the green LEDs. There is a button connected to INT pin of ATmega16. If you press it for a while, the MCU suspends itself."
