I would like to build a sort of clock with one needle and read its position on 360° (the needle can be rotated clockwise and anticlockwise without stopping, with your hand).
I tried potentiometers but they stopped, then I tried a rotary encoder but if you don't turn it slowly it is totally lost. What could I use ? Is there a motor that can deliver the position of its angle if you turn it FAST manually?
I heard about encoded motor, maybe it makes the job
