Arduino LED MIDI Controller

It's been a while since I've made a post so I have decided that it was about time I did. This time I'll be talking about my Haunted House I made.

I started with the idea to take a Halloween decoration (small haunted house) and add some LEDs to it and make them blink. What I ended up with was a haunted house with 6 LEDs in it all controlled by MIDI. I used an Arduino to receive MIDI signals from my computer and turn on/off LED lights based on those signals.

Check out the video...




The "MIDI to Arduino Breakout Board" as I call it in the video I designed myself. I used various resources on MIDI around the web and came up with this schematic.




Digikey Part list:

2 x DIN5 - CP-2350-ND
2 x 6N138 - 516-1600-5-ND
1 x diode - 1N914B-ND
2 x 220 ohm resistor
1 x 270 ohm resistor


As you can see it isn't very complicated. The hardest part was finding in DIN5 part numbers at Digikey. The code on the other hand was a bit more complicated. The trick was to decode the …
