A (pretty bad!) rendering of Jingle Bells on a piezo speaker

Documentation

jingleBells :: [(Note, Duration)]

Notes for jingle-bells. Expecting a nice rendering from this encoding on a piezo speaker would be naive.. However, it's still recognizable!

main :: IO ()

Play the jingle-bells on a PWM line, attached to pin 3. We use a tempo of 75; which is fairly fast. For a slower rendring try 150 or higher values.

The circuit simple has a piezo speaker attached to pin 3.
