#248: Passive Buzzer Module

R16.80


An active buzzer will generate a tone using an internal oscillator, so all that is needed is a DC voltage.

A passive buzzer requires an AC signal to make a sound. It is like an electromagnetic speaker, where a changing input signal produces the sound, rather than producing a tone automatically.

To identify them, if you apply a DC voltage to them and it buzzes, it's an active.

PWM on the Arduino can be used to control the pitch and the volume.
