Raspberry Pi Game Night Timer with LEDs - DIY Tutorial

Speed up game night with a DIY turn timer! On game nights, do you have that friend or family member who takes way too long on their turn? Meet Game Night Buzzer—a DIY, one-button, chess-clock-style timer. Press the button, your turn ends, the next player’s countdown starts. #RaspberryPi #RaspberryPiProjects #DIYElectronics #BoardGames #GameNight In this episode, we build the Raspberry Pi LED Turn Timer with a single button and a buzzer: green when you’re good, yellow when time’s running low, red at zero—with a beep to end the turn.
