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.
