Passive Piezo Buzzer Module for Arduino Tones and Alarms

Passive Piezo Buzzer Module for Arduino Tones and Alarms

Add audible feedback, alarms, or even simple melodies to your electronics project with this versatile Passive Piezo Buzzer Module. Unlike an active buzzer that can only produce a single tone, a passive buzzer gives you full control over the sound it produces.

This module requires a changing electrical signal, such as a square wave from a microcontroller’s PWM pin, to generate sound. By varying the frequency of this signal, you can make the buzzer produce a wide range of tones. This allows you to play simple songs, create distinct alarm sounds, or provide nuanced auditory feedback for user interfaces. The board is incredibly simple to use, requiring just a VCC, GND, and an I/O pin from your Arduino or other microcontroller.

If you want more than a simple beep and wish to have creative control over the sounds in your project, this passive buzzer is the perfect choice.

Key Features:

• Type: Passive buzzer (requires a frequency signal to produce sound).
• Full Tone Control: Generate tones of different frequencies and pitches.
• Simple Interface: Easy to drive with a single I/O pin from a microcontroller.
• Operating Voltage: 3.3V to 5V.
• Compact Size: Small module is easy to fit into any project.

Applications:

Ideal for creating custom alarm sounds in security systems, providing auditory feedback for button presses, playing simple melodies and game sound effects, or as a basic audio indicator in robotics and automation.
