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.

These are the circuit diagrams for making circuit using :

• IC 4017
• Toggle Switch

• 555 Timer IC - combination of Transient Clap Switch and Latching Circuit

These are the Components Required for making circuit :

1. Using IC 4017

• IC 4017

• Condenser Microphone

• Transistor: BC547 (2)

• Resistors: 100K, 1K (2), 330Ω

• LED

2. Using 555 Timer IC

• 555 Timer IC (2)

• Condenser Microphone

• Relay (6V)

• Diode (1N4007)

• Transistors: BC547

• Resistors: 100K (2), 47K, 10K (2), 1K, 330 Ω

• Capacitor: 1 μF (2)

• LED

Other Requirements:

• Batteries: 9V (2) and battery clips

• Breadboard

• Breadboard Connectors
