Pixel Bend Project: MIDI Issues

For about a week I was really sad. I could not get any midi data in no matter what. After rebuilding the circuit4-20 times I decied to be smart and start replacing parts. Turns out I had a bad IC chip. When I replaced the optocoupler data started flowing in like water down the Nile. But what was it?…..

I don’t know. It didn’t look like the mythical MIDI data I had heard about, instead showing up in the serial output as cryptic characters and sometimes only question marks. What to do?

    Hey Ryan,
    That sucks about the bad opto-coupler, troubleshooting circuits can be a pain. I definitely don’t trust myself sometimes and do the same thing. Did you get this to work?
