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 ...

What is a rotary encoder? A rotary encoder (RT) is a device that you can rotate infinitely. On most rotary encoders, when you rotate them you will feel a bump (known as steps), and most RTs have about ...

Experimenting with an HF oscillator, I needed to control the varactor diode voltage in precise increments over a 2V-10V range. A buffered potentiometer was the obvious choice, and connecting two pots ...

In this video, we will replace the rotary encoder on a car radio that was broken and it was jumping steps and jumping back to ...

Encoders are a vital component in many applications that require motion control and feedback information. Whether a system’s requirement is speed, direction, or distance, an encoder produces control ...

Anyone searching for a way to connect multiple rotary encoders on the I2C bus, may be interested in a new piece of hardware created by Simone based in Turin, Italy. The aptly named I2C Encoder V2 ...

Somewhere between the onset of annoying hand pain and the feeling of worn-out, mushy switches, [sinbeard]’s keyboard dissatisfaction came to a head. He decided it was time to slip into something bit ...

This is the first of a two-part series. Part 2 can be found here. Encoders play an integral role in almost every mechanical system that involves motion monitoring or control. There are a variety of ...

The sensing mechanism in an incremental optical rotary encoder consists primarily of a light source, code wheel, and optical detector. As the code wheel turns, a ring of alternating opaque and ...
