Two Clap ON - Clap OFF Circuits - 555 IC | 4017 IC

Clap ON - Clap OFF circuit is the circuit which can be used to control variety of electronic equipment by just a CLAP. One clap turns the load ON and another clap turns it OFF.

It's very common and simple to make this circuit using IC 4017, but here, I'll also show you how to make it without the 4017 IC, but by using very common IC - 555 Timer IC.

Step 1: Circuit Diagram

These are the circuit diagrams for making circuit using :

  • IC 4017
  • Toggle Switch

Step 2: Components
