Piezo Sounder component
Drives a simple variable frequency piezo sounder in hardware and simulates the sound in simulation. To actually drive a piezo you may have to amplify the signal from the microcontroller using a transistor or MOSFET.
Examples
Here is a simple example that will create a siren effect using a piezo sounder.
Piezo Siren
Depending on your Piezo Sounder you may need to amplify the signal from the microcontroller using a NPN transistor or N channel FET.
