How to the Use the Sound Sensor Module

The sound sensor module utilizes a microphone to sense any sounds. In this guide, we will be using the Sound Sensor Module from our shop.

Partsā€‹

Wiring Guideā€‹

Step 1: Connect the sensor pins to the Arduino

SensorArduino
GGND
+5V
D0Pin 3

Programmingā€‹

Step 1: Declare the pin connected to the sensor as well as a boolean value

int sensorPin = 3;
boolean val = 0;

Step 2: Activate the pin connected to the sensor as well as activating the serial monitor

void setup(){
pinMode(sensorPin, INPUT);
Serial.begin(9600);
}

Step 3: Read the sensor pin and put the value into val

val = digitalRead(sensorPin);

Step 4: Create an if/else statement for when the sensor hears sound

if (val == HIGH) {
Serial.println("ON");
}else{
Serial.println("OFF");
}
delay(1000);

Full Codeā€‹

int sensorPin = 3;
boolean val = 0;

void setup(){
pinMode(sensorPin, INPUT);
Serial.begin (9600);
}

void loop (){
val = digitalRead(sensorPin);
if (val == HIGH){
Serial.println("ON");
}
else{
Serial.println("OFF");
}
delay(1000);
}
