Hello all, thanks in advance for any advice or guidance you can give me.
I'm new to Arduino and the maker world, so I'm not sure what components are available off-the-shelf, and I haven't yet found what I'm looking for - and I'm not sure if I'm using the right keywords to look for it.
Imagine, if you will, a circular LCD or even just a basic push-button, surrounded by a rotating ring. For example, an aviator's watch or diver's watch will have a rotating ring around the watch face. In such a case, a wheel with a central axle wouldn't be practical.
Are there any off-the-shelf parts or techniques that would be available to accomplish such a feature?
The only thing I can think of right now is 3d-printing a ring with an inner gear that engages some sort of volume wheel or mouse ball type sensor, with some other support mechanism like a track or contact points to maintain concentricity.
