Corn Hole 2 Turbo: My First Steps in Embedded
summary
A Corn Hole electronic scoreboard implemented with an Arduino Uno and a 32×8 LED matrix shows scores via Bluetooth to an Android app. RFID tagging was tried but failed to distinguish cups on/off board, so the project explores camera/ML and weight-sensor approaches (noting sack weights ≈400–430 g) for automatic scoring. The prototype runs ~439 lines of C (~12 kB), added a rotary encoder for brightness and interrupt-driven responsiveness, and faced memory, contact and resin-damage issues.
