Precisely tracking speed, acceleration, and position of a motor's rotor is an essential requirement for many motor control applications found in everyday equipment such as fax machines, elevators, and ...

The encoder delivers data for display or data that may serve as feedback in a motor-control system. Such information is supplied to a host microcontroller for processing according to the application.

That’s the idea behind this Arduino-based measuring jig for fabricating parts for a CNC build. When it comes to building on the cheap, nobody holds a candle to [HomoFaciens].
