KY-006 Passive Buzzer Module

The KY-006 Passive Buzzer Module is a compact sound output module designed for use with Arduino and other microcontrollers. Unlike an active buzzer, the KY-006 does not contain an internal oscillator, meaning it requires a PWM (pulse width modulation) signal to generate sound.

This allows you to produce different tones and melodies by varying the signal frequency, making it ideal for musical projects and customizable audio alerts.
