Quick Overview
This DIYables passive piezo buzzer module generates tones and melodies through programmable frequency control from Arduino, ESP32, ESP8266, and Raspberry Pi. Unlike active buzzers, passive buzzers require a PWM signal to produce sound, allowing you to create different pitches and musical notes.
The module features convenient mounting holes for secure installation in projects and operates on 3.3V-5V, making it compatible with most microcontrollers. The 3-pin interface (VCC, GND, Signal) provides simple connection to digital output pins with PWM capability.
Ideal for alarms, notifications, musical instruments, ringtones, and interactive sound effects. The passive design enables frequency control for creating melodies, beeps, and custom sound patterns in your projects.
