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
Step 3: Build.
- Measure out how much material you have with the copper tape. Make sure you leave enough enclosure/foam to accommodate for the spaces in between to prevent shorting.
- Cut that much tape and maybe a millimeter more.
- Divide the tape into eight sections by folding.
- Solder ONE wire to each piece of tape.
- Solder male headers to the tape. Six pieces to six headers for six in puts and then a pair of two for the other two inputs; Digital 6 and 7.
- Order will now begin to matter. The first one (Analog 0) will go on the far left of the enclosure/foam. Analog 5 will go to the input 6 so it is la on the musical scale.
- Digital input 6 is ti and input 7 is high do.
