Looking for an application for the button pads, we ultimately settled on re-creating this classic. It blinks. It makes a lot of noise. And its guaranteed to suck you away from doing any real work.

This is a good demo board for our button pads, DC to DC step up, LEDs, battery holders, buzzer, pseudo-random number generator for game sequence, etc. The firmware is available below as well as schematics to see how we did it. Buy the board for a quick toy or re-write the code to create mega-Simon. Please note the board comes fully assembled as shown, tested, and includes an all important Sound On/Off switch. Battery not included - a single AA will power Simon for 15-20 hours. See our tutorials for more information about programming the ATmega8.

Software:

• Current WinAVR Firmware: Simon-v12
• Older PIC Firmware: Simon-v1 Firmware - Compilable with Free version of CC5x
