Quiz Buzzer Project Kit

2116 - Quiz Buzzer Project Kit

Kitronik Ltd.

Two people (or two teams) can use the quiz buzzer to show who pressed their button first. When the button is pressed the buzzer sounds and either the red or green light is illuminated to show who was fastest. This project is brilliant for demonstrating a wide range of electronics. It uses push to make and push to break switches, thyristors as latches, transistors, logic gates, LEDs and buzzers.
