      It’s a cool project! Thanks for sharing.

      But I was slightly disappointed that the rotary dial itself doesn’t play a role. Here’s an Arduino library for interpreting the pulse code: https://github.com/Harvie/RotaryDial

        Thanks!

        I’d like to do the rotary dial in a followup. In the meantime, you might enjoy this explanation by Alastair (starting at 9:15) in the video that I linked to in the appendix.
