In the Fall of 2020, I challenged myself to do one PCB-based electronics project a week so I can gain more experience regarding electronics projects, specifically with layout, DFA, and BOM consolidation.
This is my second project, a game of Tic-Tac-Toe! Players take turn clicking the button in the center of the square, lighting it up with either an X or O. The entire thing is controlled by an Atmega328P.
Future revisions will include an AI to play against!
