Active Buzzer Module Guide

This document describes an active buzzer module that can be driven by both DC signals and square waves to produce different sounds by changing the frequency. It operates on 3.3V or 5V, is small at 25x15x12mm and lightweight at 2g, and has a ground, power, and signal input pin. An example circuit connects the buzzer module to an Arduino pin set as output to toggle the buzzer on and off using analogWrite to produce sound.

Active buzzer module

DESCRIPTION:
It’s a basic sound component. Comparing with the passive buzzer, it can be driven by
both DC signal and square wave signal.
you can use High/Low to drive it. Just change the frequency it buzz, you can hear dif
ferent sound. It is widely used on your daily application, like PC, refrigerator,phones
and so on. And you also can create many interesting interactive project with this sma
ll but useful module.

Specification:
● Operation voltage: 3.3V/5V
● Size: 25*15*12mm
● Weight: 2g

PIN CONFIGURATION:
1、 “-” : GND
2、 “+”:+5V
3、 “S” : Signal input pin

Example:
Here is a example that driven the active buzzer sound. The connection as below:

Code:

int speakerPin = 8;

void setup ()

{
pinMode (speakerPin, OUTPUT);
}
void loop ()
{
analogWrite (speakerPin, 255);
delay (50);
analogWrite (speakerPin, 0);
delay (10);
}
