How To Use Sound Sensor ? Control LED By Clap Using Arduino And Sound Sensor

Going further to explain How To Use Sound Sensor ? Control LED By Clap Using Arduino And Sound Sensor. We are covering how to use KY-038 Sound Sensor using Arduino. Also showing how you can control LED by clap with the help of Arduino and Sound Sensor. We have shown only to control LED by clapping, but using the same concept you can control any electronic device. Once you watched full video you will understand everything.

What is KY-038 Sound Sensor ?

KY-038 Small sound sensor acts like a microphone which detects sound signals. The sensor will detect sound signals an provide digital or analog output. The sound sensor can be used to make exciting projects like clap switch or any project we can make any action based sound detection. It’s very cheap you can buy it within 2-3 USD dollar. Let’s task about KY-038 architecture :-

KY-038 Sound Sensor having 4 Pins :-

1.  AO  – Analog Output

2. G – Ground

3. + – VCC

4. DO – Digital Output

7 Components Required to Control LED By Clap Using Arduino And Sound Sensor :-

1. 1 x Arduino Uno Board
2. 1 x USB cable
3. 1 x KY-038 Sound Sensor
4. 1 x 1K Pull up Register
5. 5 x Male to Female Jumper Wire
6. 1 x Breadboard
7. 1 x LED

Connection for Control LED By Clap Using Arduino And Sound Sensor :-

Sketch/Source Code :-

int 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);
    }
  }
 }
