Active Buzzer 3V-24V
A simple buzzer for an Arduino, for example to indicate errors. With this active buzzer only an input voltage is required, no frequency. When an input voltage of 3-24V is supplied to the buzzer, the buzzer starts making sound.
This buzzer is useful when no sound pins are available.
Easy to use on a breadboard or prototype board.
