| − | 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.
