Part of my Crash Course Electronics class -- this project is based on the classic Simon color matching electronic game this project uses an AVR328p and an Arduino Compatible design loosely around the Arduino Nano to keep compatibility with the Arduino IDE. This is a more advanced design and eases you into SMT (surface mount technology) with 0805 size passives, SOICs, and large QFPs.

Additionally, the design features LDO voltage regulation, battery power, USB to serial bridge via FTDI IC, amplifier for sound, user IO buttons, LEDs, and GPIO multiplexing along with exporting out all the usual Arduino IO pins to headers, so it doubles as a fully functional ATMega 328P Arduino!
