Example Arduino code — Active Buzzer Module

This example was written and compile-checked for the arduino-uno. Codey Online adapts it to any other supported board for you.

// Canonical example for Active Buzzer Module
// Connect the module: - -> GND, + -> 5V, S -> D8

const int buzzerPin = 8;

void setup() {
  pinMode(buzzerPin, OUTPUT);
  Serial.begin(9600);
  Serial.println("Active Buzzer Module demo starting");
}

void loop() {
  Serial.println("Buzzer ON");
  digitalWrite(buzzerPin, HIGH);  // Active buzzer sounds when signal is HIGH
  delay(500);

  Serial.println("Buzzer OFF");
  digitalWrite(buzzerPin, LOW);
  delay(500);
}
