I have to thank one author of a rotary encoder decoder (Ben Buxton). While his code seemed overly complex to my untutored eye, for example creating a new data type, it did show Arduino-novice me two ...

These digital opto encoders have just two outputs with four possible logic levels (00, 10, 11, 01). The relative position of the switch is insignificant but the direction of rotation is what matters.

are only loosely related to the 0V and 5V on the Arduino. Opto-isolation is the obvious answer (until TI’s non-opto-isolators are easier to get) to remove ground voltage variations, and that got me ...

The RHDi, heavy-duty incremental shaft encoder uses precision bearings, metal code disks, proprietary custom LEDs, and custom Opto-ASIC circuitry. The RHDi, heavy-duty incremental shaft encoder ...

Makers, developers and Arduino enthusiasts searching for silent stepper drivers with high resolution encoders which are also Arduino compatible. May be interested in the new range of uStepper S ...
