The future has landed in small pixelcontroller for RGB LEDs 

ESPArtStick line are a small pixel controller designed to control a single addressable LED pixels/neopixels using a special shield and for the Wemos D1 mini. Works with FPP and xLights.

In the last few years, individually addressable RGB lights have been getting cheaper and cheaper. These lights contain a small controller chip alongside the RGB LED which makes it show a certain color. The controller chips have a serial data input and output, and can be daisy-chained together. In this way you can control many different lights using just a few control wires (rather than needing wires going to each individual light).If you’ve played around with controlling LED pixels, you know that getting the infrastructure set up to control your pixels can be quite time-consuming.
