Arduino and the Irn-Bru Can Choir present Roy Williamson’s epic anthem:
Like O Canada and The Star Spangled Banner before it, it’s a random midi file (grabbed from Midi files of bagpipe tunes: mercifully, does not autoplay) converted to RTTTL and played through a glued-on piezo.
Following on from this, here’s another anthem performed by the Five Guys and the Arduino Micro Cup Orchestra:
Converted from a midi file found at American and Patriotic Midi Music (unsurprising caution: autoplay midi music therein) to RTTL using MIDI to RTTL.
If you just want the source, here it is:

A little bit of silliness for Thanksgiving:
This took almost no time to put together. The “speaker” is a Tim Hortons cup with a cheap piezo glued to the base. What makes the Arduino sing is the Tone Library running its RTTTL demo sketch, with the anthem itself pasted in from a rather old Nokia Ringtones library.
Update: Here’s the code, such as it is. It’s just the Tone/examples/RTTTL code with the tune data pasted in. I’d been programming Arduino for about a year, so that was a semi-major achievement for me:
It’s nice to revisit old code and find it was written by a friend, Brett Hagman of Rogue Robotics.
