+ 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.
