You may find what you want on google looking for:

i-magazine picbook - Chapter 6
 

also you can toggle one of the output pins of the microcontroller on and off with little high frequency (20hz to 20khz i.e. audio frequency range) and connect it to piezo buzzer or speaker and you will notice some sounding coming out from it.
