THIS IS A SIMPLE  CLAP SWITCH  CCIRCUIT THAT USES A 4017ic DECODER. WHEN U CLAP ONCE, IT TURNS THE RELAY ON AND WHEN U CLAP AGAIN ,IT SWITCHES OFF.  SINCE THIS CIRCIT USES A RELAY, U CAN CONNECT IT TO ANY DOMESTIC ELECTRONIC APPLIANCE DEPENDING ON THE RELAY'S amp LIMIT.

THIS CIRCUIT CAN USE A REGULAR 2 PIN ELECTRET MICROPHONE OR A MICROPHONE MODULE.(MAKE SURE THAT U ONLY USE ONE OF THEM).

ALL U GOTTA DO IS JUSTSOLDER THE COMPONENTS TO THE RELEVENT PLACE

YOU WILL NEED: IC 4017, 220Ω RESISTOR (2), 680Ω RESISTORS(2), 47K RESISTOR, 1K RESISTOR, BC547 TRANSISTOR (3),  LEDS (GREEN,RED), 5V RELAY,  MALE PIN HEADERS, 3 PIN SCREW PIN HEADERS AND A LOT OF LEAD :)

THE VIDEO BELOW IS NOT MINE BUT I FU WANT TO KNOW MORE ABOUT THIS IC THEN IT'S BETTER IF U WATCH IT :)
