A hardware project documenting the design and build of a Simon game created for a fab lab in Moscow. The PCB is a two-layer board featuring four RGB LEDs, four buttons, and an ATtiny44 microcontroller. LEDs are multiplexed at 490Hz with four-bit color depth, driven via MOSFETs and managed through timer interrupts. The game logic generates a random sequence using a floating ADC pin as a seed, and the system is powered via an FTDI cable. PCB files, firmware source, and case SVG are available for download.
