In this article I will show you how to make a clap on – off light circuit. It is a very simple circuit and you can make this clap switch circuit project at home. In this circuit we will use CD 4017 IC, BT 136 Triac, BC 547 Transistor and some supporting components for making the clap on – off switch circuit. In this circuit we will connect a relay and you can connect any electric light, fan or any electrical appliances with the circuit. I will show you the complete process of making this circuit step by step.
