This library uses a PCF8575 to read the pulses of a rotary encoder. As a PCF8575 has 16 lines up to 5 decoders with a switch can be read over I2C. The PCF interrupt line can be used to detect changes ...

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 ...

I'm curious if anyone would be interested in a feature to emulate dual concentric rotary encoders using normal rotary encoders with built in push buttons? Concentric encoders are usually found on ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

Inside there’s an Arduino Uno running everything, including the two large clock faces. These are set using rotary encoders below the knobs for that analogue feel.

Rotary encoders are great devices. Monitoring just a few pins you can easily and quickly read in rotation and direction of a user input (as well as many other applications). But as with anything, t… ...

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) ...

A comparison with algorithms involving three encoders is discussed. Our system employs two rotary encoders instead of three and a yaw-rate gyroscope. Equations for generation of coordinates in free ...
