Referee lights

Former Member
Former Member over 9 years ago

Hello!

 

I am looking to make some lights that will demonstrate if a lift is good or not in the sport of powerlifting for my powerlifting club.

 

It is three referees and the lift is good or not based on a majority vote. Good lift is denoted by at least to white lights, and an no lift is denoted with at least two red lights.

 

I want to build it so that when all the referees have made their desitions the lights will come up and stay lit for 5 second.

 

Ideally it could be powered by a USB outlet.

 

I was thinking of using an Arduino, and making buttons for the referees that are red and white, with cable. Wireless is not necessary, although cool.

 

What I’m looking for is some help getting started.

    Presuming the switches are debounced, one can construct a majority gate out of a single (and some R's) comparator, or logic.
