I have a fairly straight forward art project (in principle), where i want to use a rotational sensor to determine the color of an LED. The scale though makes it a little daunting; i want to have ~400 of them in the end.
I will start with small units and work my way up, but i am worried about writing myself into a corner so i was hoping to get some community advice before i get too far.
If i want to read a knob, it seems my options are Potentiometer and Rotary encoders. The encoders seem like the best options, since they their continuous rotation (which is more robust for an interactive art piece where people will be pawing at it), however searching around it seems like they are far more expensive (was hoping ot get something around 1$ a piece), and i've never had to mux them or pots before, so im not sure if there are any complications i should be aware of.
