Gameshow Buzzer System

Post by theplaidtieninja »

I am looking to create a gameshow buzzer system. Attatched is a basic diagram of what I'm looking to do.

Main parts are 4 buzzers, 2 LED displays for team scores, 2 moderator buttons to add to teams scores and 1 moderator button to reset scores to 0.

I have several questions:

1 - Will I need to get two separate Pi Zeros?
One to run the buzzers and the other to run the score displays?

2 - Is there already a pre established code for the lockout buzzer system?
I would like only the first buzzer pressed to sound a specific buzzer sound and light up the LED in the arcade button. (https://www.adafruit.com/product/3490)

3 - Is Pi zero even the best board to use for this? Would a feather or arduino be more appropriate?

You'd be better off using a microcontroller than a Raspberry Pi.

The RasPi's operating system makes it difficult to measure time intervals smaller than about 10ms, but microcontrollers can operate comfortably down in the microsecond range. A microcontroller like the Metro can also handle all the information you want to manage, run the buzzers, and control a display with the scores:

I don't know of any existing code to do all the things you'll need, but jobs in question aren't too hard.

Awesome, I'll look into the Metro. Thanks for the input.
