Description

This module features a sensitive microphone for detecting sound. It features both a digital and an analog output. The analog pin outputs a real-time voltage signal of the microphone. The digital pin can output either a high or low signal indicating when sound intensity has reached a certain threshold. The sensitivity threshold can be adjusted via the potentiometer on the sensor.

Test Code (Digital Output)

int Led = 13; // define LED Interface
int buttonpin = 3; // define D0 Sensor Interface
int val = 0; // define numeric variables val

void setup () {
pinMode (Led, OUTPUT); // define LED as output interface
pinMode (buttonpin, INPUT); // output interface D0 is defined sensor
}

void loop () {
val = digitalRead(buttonpin); // digital interface will be assigned a value of pin 3 to read val

// When the sound detection module detects a signal, LED flashes
if (val == HIGH) {
digitalWrite (Led, HIGH);
}
else {
digitalWrite (Led, LOW);
}
}

Test Code (Analog Output)

int sensorPin = A0; // select the input pin for the potentiometer
int ledPin = 13; // select the pin for the LED
int sensorValue = 0; // variable to store the value coming from the sensor

void setup () {
pinMode (ledPin, OUTPUT);
Serial.begin (9600);
}

void loop () {
sensorValue = analogRead (sensorPin);
digitalWrite (ledPin, HIGH);
delay (sensorValue);
digitalWrite (ledPin, LOW);
delay (sensorValue);
Serial.println (sensorValue, DEC);
}
