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.

encoder.tick(); // just call tick() to check the state.

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 ...
