HOW TO MAKE ARDUINO CLAP SWITCH

MATERIAL NEEDED :-

1) ARDUINO (ANY)

2) SOUND SENSOR

3) JUMPER WIRE

4) RELAY BOARD (5V)

PROJECT DESCRIPTION :-

 In this Project  I'm  using Arduino mega 2560 version but can also use arduino uno. the connection and program remains the same (no changes).sound sensor is used to detect sound(clap), sound sensitive can be control by potentiometer connected on sound sensor. when the sound sensor detect sound(clap) the produce HIGH signal(5v) which is detect by the Arduino(microcontroller) ,then the  Arduino  turn on the relay by sending high signal to relay pin.
