The Buzzer Module is a compact and versatile sound generator used in electronics projects. It comes in two main types:
-
Active Buzzer: Produces a fixed tone when powered. Easy to use — simply connect to a voltage source or digital pin.
-
Passive Buzzer: Requires a signal (PWM) from a microcontroller to generate sound, allowing you to create different tones and melodies.
Both modules are widely used with Arduino, ESP32, STM32, and Raspberry Pi, making them essential components for signaling, alarms, or sound-based interaction in electronic systems.
🔹 Typical applications include:
-
🔔 Alarm and notification systems
-
🤖 Robotics sound alerts
-
💡 DIY projects and educational kits
-
🎶 Generating tones, melodies, or simple music
Durable, compact, and beginner-friendly, buzzer modules are a must-have for adding audible feedback to your electronics.
