How to make clap switch

ABOUT THIS PROJECT

This video shows how to use KY-038 Sound Sensor using Arduino. It also shows how you can control LED by clap with the help of Arduino and Sound Sensor. We have shown only to control LED, but by using the same concept you can control any electronic device.

KY-038 Sound Sensor having 4 Pins:

• AO – Analog Output

• G – Ground

• + – VCC

Codeint soundSensor=2;

int LED=4;
boolean LEDStatus=false;

void setup() {
 pinMode(soundSensor,INPUT);
 pinMode(LED,OUTPUT);

}

void loop() {

  int SensorData=digitalRead(soundSensor); 
  if(SensorData==1){

    if(LEDStatus==false){
        LEDStatus=true;
        digitalWrite(LED,HIGH);
    }
    else{
        LEDStatus=false;
        digitalWrite(LED,LOW);
    }
  }
 }
