Piezo Sensor based Tap On Off Switch Circuit on Breadboard | 555 Timer project #3
A Tutorial on How to make a Tap On Tap Off (or) Piezo Knock Sensor circuit that flip-flops the output whenever we tap on the piezoelectric Speaker. This circuit can also be easily converted into a touch on-off circuit so that the output state is toggled each time we touch on the sensors.
An explanation of how this circuit works is also included in this video.
