Active buzzer is a cheap electronic component able to produce a sound when powered with a DC current. Differently from passive buzzer, this element includes a built-in oscillator. This allow user to make it working by powering on and without the need to simulate an electronic square wave. It includes 2 rear pins. The longer […]

Passive buzzer is a cheap and simple DC powered element able to generate a multi tone sound if triggered with low voltage current. Passive buzzer differs from active buzzer because active one has an internal oscillator able to generate sound when simply activated with a continuous trigger. Passive buzzer, instead, needs a square wave trigger
