Tic-Tac-Toe Game with Raspberry Pi Pico

This 3D-printed Tic-Tac-Toe Game is a portable electronic version of the classic childhood game, built around a Raspberry Pi Pico. The project uses a grid of addressable WS2812B RGB LEDs and push buttons to create the game board, while an OLED display shows the game rules and score.

The device is powered by a Li-Po battery, making it possible to play without being connected to a computer or external power supply. The project combines programming, electronics, and 3D printing in a compact and interactive game.
