Make noise with a piezo buzzer. Use a digital out pin.
Fork of
beep

Peter Drescher
This is a simple non blocking library to turn on the pin passed into the constructor for the amount of time specified when calling the beep(float time) function.
I use it to turn on a buzzer but it could be used for anything you need to turn on for a set time.
