These cornhole boards react to your bean bag tosses
— November 25th, 2020
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.
