Hi Richard,
I saw people recommend Olin's Hal project,
but, you also might want to consider Roman Black's

>How can you make nice tones or sounds on a small speaker connected to one pin?
Is this possible? Square wave tones are very harse and not very musical. I would
like to have sounds kind of similar to bleeps and blurps found in Las Vegas
gambling machines.
