+  MIDI note player
+
+  This sketch shows how to use the serial transmit pin (pin 1) to send MIDI note data.
+  If this circuit is connected to a MIDI synth, it will play the notes
+  F#-0 (0x1E) to F#-5 (0x5A) in sequence.
+
+  The circuit:
+  - digital in 1 connected to MIDI jack pin 5
+  - MIDI jack pin 2 connected to ground
+  - MIDI jack pin 4 connected to +5V through 220 ohm resistor
+  - Attach a MIDI cable to the jack, then to a MIDI synth, and play music.
