MIDI for microcontrollers

MIDI, or Musical Instrument Digital Interface, is a specification for a communications protocol between digital synthesizers and other digital music devices. It was developed to be as simple and general as possible, to give synthesizer manufacturers as much flexibility as possible, yet still have their instruments talk to each other without communication problems. Here is a simple circuit for MIDI output that works well with Wiring or Arduino, the PIC microcontrollers, the BS-2, and the BASIC ATOM Pro24.
