How to build an Arduino powered RGB LED Sign | Arduino 3D Printed RGB LED Hello World Sign with WIFI

I decided to build an ESP8266 Arduino powered RGB LED 3D printed sign. This build makes use of the L0L1n (NodeMCU) board to program some WS2812B Addressable RGB LED Strips. Because these LED lights are individually addressable, we are able to control them using the FastLED Arduino Library. We can also create a web server on the ESP8266 board to control the LEDs using a web app or any other device that is capable of sending HTTP POST requests to our ESP8266 server. Since the program is build using the Arduino CLI, all of the code that powers the server and controls the LEDs is written in C/C++. The web app that controls the LED lights is built using HTML, CSS, and vanilla ECMAScript 6 (ES6) Javascript.
