In this very moment the AVR board has a simple buzzer that plays a simple sound (beep @ 2.3kHz) using a timer interrupt to generate a rectangular signal on an output pin.
Well... the problem is that the client is not very satisfied with it: he said that a simple beep is not enough; he wants the AVR to play a short tune/melody, but using the existing hardware (i.e. the simple buzzer).
So, I need your help. Anyone knows how can I do it?
Thx in advance.
