This sensor utilizes a microphone to detect ambient sound.

Specifications

Operating Voltage: 4V ~ 6V
Digital output
Sensitivity adjustable via a variable resistor

Example Required Hardware

Arduino board
Jumper cables
Sound detection module
LED
330 ohm resistor

Connection

Arduino	Sound Detection Module	LED	Resistor
5V	5V
GND	GND	K
A2	OUT
D2			connected
		A	connected

Example Code

This example toggles an LED ON/OFF when sound is detected.

const int soundPin = A2;
const int LED = 2;

void setup() {
  pinMode(LED, OUTPUT);
  pinMode(soundPin, INPUT);
  digitalWrite(LED, LOW);
}

void loop() {
  if (digitalRead(soundPin) == HIGH) {
    digitalWrite(LED, !(digitalRead(LED)));
    delay(100);
  }
}
