Interfacing Passive Buzzer Module with Arduino

Written by Mohammad Damirchi

Buzzer Features

A buzzer is a device used to produce sound. There are two types of buzzer: active and passive. In the active model, buzzer starts playing sound only if connected to a power supply, but in the passive model, we need to send a pulse from the microcontroller to play sounds.
The supply voltage of the buzzer is 3 volts, 5 volts and 12 volts.

You can download the passive buzzer datasheet here.

const int buzzer = 9; //buzzer to arduino pin 9


void setup(){
 
  pinMode(buzzer, OUTPUT); // Set buzzer - pin 9 as an output

}

void loop(){
 
  tone(buzzer, 1000); // Send 1KHz sound signal...
  delay(1000);        // ...for 1 sec
  noTone(buzzer);     // Stop sound...
  delay(1000);        // ...for 1sec
  
}
