🔊 5V Passive Buzzer – Sound Signal Generator Module

🎵 Tone Generator for Microcontroller Projects

The 5V Passive Buzzer is an easy-to-use component that generates sound through PWM signals from a microcontroller like Arduino or Raspberry Pi. Unlike active buzzers, it doesn’t have an internal oscillator, giving you full control over the tone frequency and duration.
