| 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. | |
