on video How to Make Clap Switch Light On & Off at Home | JLCPCB

In this tutorial, we are going to make Clap Operated Switch using CD4017 Decade counter IC. It consists of a condenser microphone that senses the clap sound and gives a clock pulse to the Decade counter IC which in response turns the relay ON or OFF. With the first clap IC gives the HIGH value at pin no.2 and with the second clap pin no.4 provides a HIGH value but this value is provided to reset the pin of IC. In this way, we are switching ON or OFF. This relay can switch AC loads or appliances. To increase the sensitivity of the circuit two transistors are added to the circuit. Let's make it!
