Buzzer component

Drives a simple fixed frequency buzzer in hardware and simulates the sound of a buzzer in simulation. To actually drive a buzzer you would have to amplify the signal from the microcontroller using a transistor or MOSFET.

Detailed description

Examples

Depending on your Buzzer you may need to amplify the signal from the microcontroller using a NPN transistor or N channel FET.
