Ball Wall Game is a simple Arduino-based project that uses an OLED display and button inputs to control a ball within a bounded area. Players can move the ball using four directional buttons while staying within the defined limits. The project demonstrates graphical rendering, input handling, and basic game mechanics on microcontrollers. Built using the U8g2 library, the game is optimized for a 128x64 OLED screen with I2C communication. It's a fun and interactive way to showcase embedded systems programming and hardware integration skills.
