Active Buzzer Features
A buzzer is a device used to produce sound. There are two types of buzzer: active and passive. In the active model, buzzer starts playing sound only if connected to a power supply, but in the passive model, we need to send a pulse from the microcontroller to play sounds.
The supply voltage of the buzzer is 3 volts, 5 volts and 12 volts.
