Quiz Show System

The system is made of 3 quiz stations with big red pushbutton and lights, and a controller.

The competitor reserves to answer the question by pushing the button, his lights turn on and a sound is emitted. Then the other stations are disabled, until the presenter resets the system.

This project was committed by the Comune of Casarsa.

The system has been projected with totally electro mechanical circuits, no digital ICs. So it is simple concept, reliable, and can be expanded with digital controls in a future.
