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 ...

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 ...

Adafruit has made an I 2 C interface for four rotary encoders. It comes in the form of a PCB with four footprints that accept one of the most common rotary encoder forms (Bournes PEC11 horizontal ...

Because encoders limit the number of controls required to increase functionality, they reduce the real estate needed in a given piece of equipment and, in turn, can reduce the point of focus or ...

It’s difficult to nail down exactly what counts as a “real” cyberdeck in this brave new era of bespoke computing. But at the minimum, most in the community would agree that a proper deck should have a ...

In the era of touch screens and capacitive buttons, we’d be lying if we said we didn’t have the occasional pang of nostalgia for the good old days when interfacing with devices had a bit more heft to ...
