Arduino MIDI Out
My first attempt at building a MIDI Out controlled by a button
|
Wanted a simple MIDI Out for sending MIDI messages to a drum machine. The button can be used to toggle the messages on/off. http://www.tigoe.com/pcomp/code/communication/midi/ was immensely helpful. |

I just glanced at your sketch. Two initial thoughts: 1) the resistor to the MIDI port goes on the +5V, not ground. 2) In your sketch, with the ground and voltage wires at the bottom (going from the Arduino to the perf board, both are landing on the same row on the perf board.Brian Kelly # Oct. 1, 2012, 4:35 p.m.
Okay, I see #2 and will adjust that. Probably messed it up when I was trying to make the layout look nicer. As for #1, I got to this circuit by going through a few conflicting circuit designs online before I found one that works. I had started with http://itp.nyu.edu/physcomp/Labs/MIDIOutput which shows the resistor on the Ground. Then I found http://www.tigoe.com/pcomp/code/communication/midi/ which has different wiring which ended up working for me but I didn't notice the placement of the resistor change. I will update this. Thanks for your comment. I am just getting started with Arduino and it's nice to get some feedback!Brian Kelly # Oct. 2, 2012, 3:48 a.m.
I've updated the diagram per your comments. Thanks!
