The lawn game of cornhole has seen a surge in popularity over the last couple of decades. But if you’ve ever thought about raising its cool factor, then YouTuber Hardware Unknown has just what you’ve been waiting for: light and audio effects that react to your throws.
Hardware Unknown’s foldable boards each feature an Arduino Nano for control. A vibration sensor is used to tell when a bean bag hits the board, and an IR break-beam setup senses when one goes into the hole.
After a shot is made, the board “celebrates” by blinking its built-in LED ring and the strips of white LEDs that were added along the edges, while victory sounds are produced with the help of an MP3 module and a small speaker. A pair of nRF24L01 radios are also implemented to coordinate signals between both Arduinos and properly activate the opposing board’s sequence.
More details on the project can be found in Hardware Unknown’s video below!
