Audio Sensor Arduino Compatible

This Arduino-Compatible Audio Sensor is equipped with a microphone for sound detection. It offers both digital and analog outputs. The analog pin delivers a real-time voltage signal corresponding to the microphone's input. Meanwhile, the digital pin provides a high or low signal based on preset sound intensity thresholds. Users can adjust sensitivity thresholds using the sensor's built-in potentiometer.

Test Code

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);
}
}
