5v Relay Clap Switch Circuit

5v Relay Clap Switch Circuit with CD4017 IC

The heart of this Clap Switch Circuit is a CD4017 IC. A CD4017 IC is a 16 pin CMOS decade counter/Divider IC with 10 outputs. It is also known as the ‘Johnson 10 stage decade counter’. It has 10 decoded outputs that give output signals one by one in sequence when a clock signal from the clock input is given.

Step 1: Useful Steps

1) Solder the 16 – pin IC base on the PCB board

2) After that, place the CD4017 in the 16 – pin IC socket.

3) Solder all the resistors on the PCB board.

4) After that, solder the BC547 transistors on the PCB board.

5) Solder the 1N4007 flyback diode on the PCB board.
