About this project
Build a joystick-controlled pixel art canvas on a 128x64 OLED screen. Move the analog joystick to draw or erase pixels, press the joystick shaft to toggle DRAW/ERASE mode, press CLEAR to wipe the canvas, and press SAVE to store your drawing in EEPROM so it survives power-off. The WOW moment: draw your college logo at an exhibition, press SAVE, power off, power back on -- the drawing returns exactly as you left it. Under the hood the canvas is a 1024-byte packed bitfield that fits perfectly in the Arduino's memory and matches the OLED controller's own page format. Build time: 2-3 hours. No WiFi, no app, no cloud.
