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 them met my needs, so I have ...

We are surrounded by rotary encoders without even realizing it, as they are used in many everyday items, from printers and cameras to CNC machines and robots. The most common application for a rotary ...

This library uses a PCF8575 to read the pulses of one or more rotary encoders. As a PCF8575 has 16 lines up to 5 rotary encoders with a switch can be read over I2C. The PCF interrupt line can be used ...

I would like to read the "Rotary Encoder with LED (Red) with Knob Set" available at Akizuki Denshi Tsusho using an ESP32. In two previous articles, I implemented this using polling and was able to ...

Number of counts (pulses) per full revolution of the encoder knob. Each count corresponds to a small increment of rotation. Which direction is the wheel turning? A positive positionChange indicates ...
