Default Re: Quick n dirty coil winder

It actually doesn't matter on the sensor technology used, be it magnetic, optical, or other. You still need two sensors to sense direction, sensor A and sensor B mounted apart, this works by sensing the 'firing order' of each sensor where either sensor A fires first and then sensor B fires second for one direction, or vice versa SB then SA for the other.

Another way of doing it with a DC motor is to sense polarity at a point on said DC motor, ie. + for increment and - for decrement, or whichever way round that suits.
