This experiment is about generating a melody tune using a PIC microcontroller. Well, this won't be difficult if you know the notes of the tune, and their respective frequencies. Here's a chart for note to frequency conversion. We will play the 'Happy Birthday' tune with a PIC12F683 microcontroller. The microcontroller will generate the frequencies of the various notes (with proper timing) in the tune and the melody will be played in a piezoelectric buzzer.
Circuit Setup
The piezo buzzer is connected to the GP2 port of PIC12F683.
