The Sound Sensor Module, is an microphone integrated into an electronic circuit, used to detected Sound signals.
So that it is used in many devices to capture and record sound, and it can also be used to control electronic circuits by sound.
In this post we will learn: How To Use Sound Sensor With Arduino.

Electronic components needed :

1 Resistance ( 220 Ohm )
1 Led
Sound Sensor Module KY-038
Electrical wires
Arduino UNO
Breadboard

Schema of the circuit :

Arduino programming code :


const int ledpin=11; 
const int soundpin=A2;
const int threshold=200;
// By www.andprof.com
void setup() {
Serial.begin(9600);
pinMode(ledpin,OUTPUT);
pinMode(soundpin,INPUT);
}
void loop() {
      // reads analog data from sound sensor
int soundsens=analogRead(soundpin);
if (soundsens>=threshold) {
      //turns led on
digitalWrite(ledpin,HIGH); 
delay(1000);
}
else{
digitalWrite(ledpin,LOW);
}
}
