Hi Guys! I'm trying to get MIDI input into an arduino using this instructable
And one's I've found like it. I can't for the life of me figure out why it's not working. I'm trying to run the program under the midi input schematic to simply have the Pin 13 led turn on when it receives MIDI number 60.
I think the problem lies somewhere in getting output from my optoisolator. I've probed the input of the isolator, and I appear to be getting some input into the isolator. But all I get is 5v on the output, nothing that looks like it could be serial data. I've checked my wiring around a million times, and I'm fairly certain that I'm wiring it up correctly. Any ideas? Thanks!
