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
No detailed description exists yet for this component
Examples
Depending on your Buzzer you may need to amplify the signal from the microcontroller using a NPN transistor or N channel FET.
A basic buzzer example using all the buzzer functions.
It should be noted that if you have a single BuzzerOn component with no loop, the buzzer sound will stop when the simulation stops.
The pin will remain high.
While the buzzer is on, the simulation tone is not continuous, it rapidly pulses, the pin will remain high.
That is not a bug with the component
