Quiz Buzzer in Action
A quiz buzzer I made is being used in Access 2015, computer symposium of Modern School, New Delhi, India. The video is not clear but you can sort of see the buzzer on the stage. Whenever a contestant presses a button, a buzzer is sound followed by the switching on of the corresponding light bulb.
