Midi Board ==================================================

Here is another midi-in, midi-out and midi-thru-circuits for the Arduino. It is made with the opto isolator 6N138 and the inverter 74LS04N. To prevent bootloading confusion always powers the opto isolator over the Arduino. Depending on the position of the jumper the board can be used for Midi Out or Midi Thru. Two LED indicates Midi In and Out. One if the board is powered.
