The video is a primer on encoder design, walking you through the basics of sensing rotation with phototransistors, and how a pair of detectors is needed to determine the direction of rotation.

Spinning the rotary encoder cycles through a menu of programs on the 16×2 LCD, and the key map just updates automatically for the chosen program.

Absolute Encoders The advantage of absolute rotary encoders is that they provide unique position values as soon as they are switched on by scanning the position of a coded element.

Figure 1 The rotary encoder controls a staircase waveform with precisely defined steps The outputs of an incremental encoder typically consist of two signals in quadrature (i.e., phase-shifted by a ...

Need a rotary panel control that automatically switches between fine and coarse adjustment? It's here.

Rotary encoder decode for Arduino 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 ...

Hirschmann's new gSENS DWG 20 rotary encoder uses optical sensors to break down one revolution of a shaft, of a hoist or slew drive unit, for example, into 8192 increments.

Encoder technologies abound, but software, wiring, and embedded microprocessors let designers tailor magnetic-encoder performance to application requirements.

The SKM 36 SinCos Motor Feedback System is a multi-turn rotary encoder that tracks absolute position over 4,096 turns. The SKM 36 features a minimum number of components to allow miniature and ...

Rotary encoders are used to measure angular position or speed for control and feedback purposes across a wide range of applications. Modern designs favor non-contact sensing methods ...

Electronic enthusiasts, hobbyists and engineers looking for an open source rotary encoder complete with a circular 1.2 inch programmable TFT circular display may be interested in the Roendi.
