The encoders and jacks arrived for the synthesizer module I’m working on. I have found many examples of code for getting the encoders to work with the Arduino, but they’re all different, and they’re all unclear about wiring. Off to figure that out.
(In the background at the top right of the upper photo is another attempt at the panel using the matte acrylic. It’s a lot harder to make a readable panel this way, but the matte surface gets far fewer fingerprint smudges.)
