I am working on a project where we have modelled a man in foam. The arms needs to be able to go up and down in one direction. We want to be able to control the position of the arms by a motor, but we also want to be able to physically pull them up and down, and read the position.
Right now we use a potentiometer to read the position, and we can move the arms up and down physically. Is it possible to implement a motor, so this also can be done by code? Our concern is, that the motor is not built for being manipulated.
We are using an Arduino Uno.
