Overview This project demonstrates how to measure the RPM (Revolutions Per Minute) of a rotating object using an optical encoder with an Arduino. The code counts pulses generated by the encoder and ...

A rotary encoder is a wonderful digital alternative to the old analog potentiometers. Rotary encoders are useful as rotation sensors (or selectors) and look similar to potentiometers, but rotate all ...

In this article we are going to discuss how rotary encoder module works and how we can use interface it with Arduino. This tutorial contains Circuit connection and Arduino Code.

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 needed a rotary encoder — I pulled a cheap one out of one of those “49 boards for Arduino” kits you see around. Not the finest encoder in the land, I’m sure, but it should do the job.

We made a digital Measuring Wheel using the rotary encoder in this tutorial. Digital Measuring Wheel can help us measure the length it traverses with millimeter-level accuracy.
