In the buzzer round of quiz contests, the question is thrown open to all the teams.The person who knows the answer hits the buzzer first and then answers the question. Some times two or more players hit the buzzer almost simultaneously and it is very difficult to detect which of them has pressed the buzzer first
.
For this reason buzzer rounds are avoided for quiz contests held in colleges. This project is an electronic quiz buzzer that is affordable by the colleges and even individuals. This project is useful for a 4-team quiz contest, although it can be modified for more number of teams. This system is sensitive. The circuit can detect and record the first hit contestant among all the contestants that may appear to be simultaneous.
sorry for annoying buzzer sound.
Any questions feel free to ask in comments!
