A wireless quiz system using low power microcontrollers

One of the many important parts of any multi-participant quiz game show is the Player Selection System. All participating groups are equipped with a selection button placed in front of them which can be used by them to give a response. The Player Selection System determines the group that gives the first response. Many of these systems used today are wired systems that consume a considerable amount of power. This paper describes an easily installable, expandable robust wireless quiz system using a low battery-powered microcontroller interfaced with a RF wireless transmitter.
