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 ...

Motion-control or industrial automation system designers who need to measure the rotation of shafts or other mechanical components can typically choose from two types of rotary encoders. Encoders ...

Precisely tracking speed, acceleration, and position of a motor's rotor is an essential requirement for many motor control applications found in everyday equipment such as fax machines, elevators, and ...

Optical rotary encoders are the most widely used way to transform mechanical rotary motion into electrical signals. There are three basic configurations for optical encoders: incremental, absolute, ...

HEIDENHAIN’s RENCO brand of encoders are well suited and available for use within a variety of mobile robot applications. Specifically, the modular RENCO R35i and RCML15 rotary encoders have proven ...

Adafruit has made an I2C 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 style) ...

Not every project has to be complicated– reinventing the wheel has its place, but sometimes you find a module or two that does exactly what you want, and the project is more than halfway done. That ...

The ECI 119 is an absolute, inductive rotary encoder with a low profile (height of 19mm, outside diameter 92mm) and large through shaft (50, 38, or 30mm), making it well suited for electric motors in ...

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 ...
