Quiz buzzer

Open project · after lesson 8: Radio duel

Make buzzers for a class quiz: each team has a micro:bit, the first team to press its button wins the turn, and every other buzzer knows it lost. A quizmaster micro:bit can reset the round.

One way it could look. Yours will be different.

Milestones

Tick each one when it is true of your project. Nobody marks it: be honest with yourself.

Pressing a buzzer sends its team's number by radio.
Only the first press counts: later presses are ignored until the round is reset.
Every buzzer shows who won, and a reset starts a new round.

Make it yours

A different sound for each team.
The quizmaster's micro:bit keeps the score.
A time limit: no buzz in 10 seconds shows a clock.
