This tutorial explains how to use Sound Detection Sensor with Arduino
1. Introduction:
The Sound Detector is a small board that combines a microphone and some processing circuitry. It detects the sounds of door knocks, claps, voice or any other sounds loud enough to picked up by the microphone.

int soundSensor = 2;
int LED = 4;
void setup()
{
pinMode (soundSensor, INPUT);
pinMode (LED, OUTPUT);
}
void loop() {
int state=digitalRead(soundSensor);
if(state==1) //when detect some sound
{
digitalWrite(LED, HIGH);
}
else
{
digitalWrite(LED, LOW);
}
}
5. Output
When sound of clapping or any other is detected by sensor, the led attached to module will illuminate.
