Is it really possible to build a rotary encoder out of a flattened tin can and a couple of photodetectors? Sure it’s possible, but what kind of resolution are you going to get from such a contraption?

It is amazing how many Arduino programmes for decoding rotary encoders start with something like: “I looked at all the available rotary encoder sketches and none of them met my needs, so I have ...

An incremental rotary encoder converts angular motion or the position of a shaft to either analog or digital code. Incremental encoders are often used in feedback systems. These encoders translate ...
