On game nights, do you have that friend or family member who takes way too long on their turn? Do you wish you had an automatic buzzer to keep things moving?
Welcome to Game Night Timer—a DIY, one-button turn timer for board and card games. Press the button, your turn ends, and the countdown for the next player begins. In this episode, we’ll build an Arduino Uno LED & LCD Turn Timer with a button and a buzzer:
🟢 Green = you’re good
🟡 Yellow = time’s running low
🔴 Red = you’re out
🔔 Buzzer = turn is over
