We are surrounded by rotary encoders without even realizing it, as they are used in many everyday items, from printers and cameras to CNC machines and robots. The most common application for a rotary ...

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 ...

What is a rotary encoder? A rotary encoder looks like a potentiometer, but it is fundamentally different. A rotary encoder can rotate freely unlike a potentiometer and instead of variating resistance, ...

This is a very original, effective, and interesting example of a safe lock, which is almost identical to the large factory safes. Rotary dial safes typically use a mechanical combination lock. They ...

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?

I would like to read the "Rotary Encoder with LED (Red) with Knob Set" available at Akizuki Denshi Tsusho using an ESP32. In two previous articles, I implemented this using polling and was able to ...
