I'll show you how to make a wireless quiz buzzer system using nRF24L01 modules and Arduinos.
The buzzers are totally self-contained including a built in lithium battery with charger.
Part 1 was a wired version
The main controller, also wireless, now has the option to disable buttons from people who have already guessed an answer and has a 3.5" socket to connect the audio output to an external amp.
I've also left the USB port exposed for future use in case I want to build an application that can use the button data in real time as well as control them
