Special thanks to Joe Marshall who wrote the very useful code.
As suggested in the title, it runs on Arduino.
So before we get started, let's see what is sounds like. Shall, we?
And and explanation would be nice.
Step 1: Parts of The OctoSynth.
12 Male headers (2 together and another six together. Also, another 4 together(Optional))
8 Unifomly LONG Wires ( By long I don't mean 3 meters but it means a decent 10 inches or maybe, 20 crentimeters.)
A Certain Amount of Copper Tape (Get a roll to be safe)
Enclosure (I used styrofoam as a base but if you want an enclosure, which is totally fine, you can use one. The length will depend on the wideness of you choose.)
Power Jack and Battery
