Hello, I am doing a project in which I have an encoder (ky-040), I would like that when a signal arrives to the arduino it makes resistance to the rotation of the encoder shaft.
I don't know what hardware to use to make it more difficult to rotate the shaft, I would like to feel that it is more difficult to turn the axle. (I'd like it to be somewhat noticeable but still be able to rotate without any problem).
I would like to know if someone can give me an idea or a design to do it. I can't think how I could do it, with a motor...?
