Nomis: Simon game clone on ATTiny85
Christopher Woodall from HappyRobotLabs wrote in about his recent project, Nomis, a Simon clone made using an ATTiny85.
It uses up 4 pins, 3 for LEDs and 1 for buttons (ADC input). The write up can be found here. Everything is completely open source (except for the EAGLE CAD limitations of course, which kind of suck) and I am currently waiting on some PCBs to be made.AVR, DIY and tagged Attiny85, simon game.
