5V Buzzer Module (Active) The Buzzer Module is a converted version of the active buzzer that you can use for sound output in your Arduino projects.
With the buzzer module that you can use in warning systems, your applications will make noise in Arduino or different microcontroller works. The buzzer will start to sound when the I/O pin is triggered with 5V or 3.3V. You can either directly connect it to the 5V or 3.3V power line on the Arduino board or provide 3.3V or 5V to the module externally.
