A rotary encoder is a type of electromechanical position sensor that can be used to identify the angular position of the rotary shaft. This type of sensor or module generates an electrical signal ...

A Rotary encoder is an input device which helps the user to interact with a system. It looks more like a Radio potentiometer but it outputs a train of pulses which makes its application unique. When ...

This project is written for Python 3. The Pi Zero needs to be configured to use SPI (cardd reader) and I2C (OLED). I used this library for KY-040 and this one for the RC522 reader. The adafruit OLED ...

This ESP32 component uses a debouncing state machine to track the position of an incremental rotary encoder such as the EC11 or LPD3806. These encoders provide two outputs (typically "A" and "B") that ...

As you may have noticed, I’ve been working with an STM32 ARM CPU using Mbed. There was a time when Mbed was pretty simple, but a lot has changed since it has morphed into Mbed OS. Unfortunately, that ...

Here is a trick that allows you to connect one or more rotary encoders to a microcontroller while using only one (1) analog input. Here is a trick that allows you to connect one or more rotary ...

Rotary encoders sense changes in the position of a rotating shaft, then generate signals that send speed, direction, and position information to a receiving device such as a counter, drive, or ...

[Long Haired Hacker] has undertaken a high-resolution 3D printer build. He got his hands on some motors to drive the build platform but it doesn’t have a built-in encoder. He knows that optical ...
