Learn how to use NeoPixel rings with Arduino UNO and a rotary encoder. NeoPixels are great, because you need only one data wire to control any number of pixels you want, allowing to show any color.

What is a rotary encoder? A rotary encoder (RT) is a device that you can rotate infinitely. On most rotary encoders, when you rotate them you will feel a bump (known as steps), and most RTs have about ...

“I looked at all the available rotary encoder sketches and none of them met my needs, so I have written my own, and here it is”. Well, I looked at all the available rotary encoder sketches and none of ...

Working voltage: 5V; One round number of pulse: 20 The rotary encoder can count the number of pulse output during rotation in the positive direction and reverse direction through the rotation and this ...
