Arduino UNO R3 + NeoPixel ring + Rotary Encoder = Something Nice Learn how to use NeoPixel rings with Arduino UNO and a rotary encoder. NeoPixels are great, because you need only one data wire to ...

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 ...

A fun fidget thing made with Arduino IDE with Neopixels - Ordinary3/Rotary-Encoder-NeoPixel-Fidget ...

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 ...

Rotary encoder (s) on a single MCU pin 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 ...

An incremental rotary encoder requires two (microcontroller) inputs for decoding the rotational direction and speed. Three inputs are needed when it has an integrated pushbutton. In this video we show ...

The main components are the Adafruit Trinket M0 microcontroller and the EC11 rotary encoder itself. To provide nice visual feedback he added in a NeoPixel ring, but that’s not strictly necessary ...

That’s the idea behind this Arduino-based measuring jig for fabricating parts for a CNC build. When it comes to building on the cheap, nobody holds a candle to [HomoFaciens].
