hello everyone, first time posting in these forums so hopefully I won't ask to many silly questions
I've been trying to get kuk's midi input circuit going but I'm having problems, and the most frustrating thing is that it's unclear to me how to debug this. I'm a novice at this stuff, and I'm trying to use midi input with the arduino for an art project / interactive music installation so any guidance would be greatly appreciated.
As of right now, I'm never getting Serial.Available on the RX input pin (using digtial pin 0).
Some of the steps I've tried:
1) I've verified my input pin works using a simple potentiometer. I can get Serial.Available to read an input byte with that set-up
2) I've tried both midi plug wiring options as described in this thread.
3) I've tried the circuit with and without the diode.
Now I had access to several 2W resistors. These things are funny looking becuase they are so fat. Is it possible these could be overbuilding the circuit and causing it to fail?
I do not have access to a scope, but I do have a multimeter. Are there any obvious debugging points that I should try?
Thanks for any help you guys can give,
