Alexa RGB LEDs (WS2812B) Rainbow Light With 3D Case

In this project, we will connect a programmable RGB LED strip to the Lolin NodeMCU V3 board and program it to show rainbow colors. We will also create a 3D printed enclosure to make it wall lamp.

1) Addressable RGB LEDs (WS2812B)

2) Wemos D1 Mini (or any other ESP8266 Arduino board)

3) Dupont and USB cables

You need the following libraries for this project:

1) FastLED: https://github.com/FastLED/FastLED

2) Aircoookie Espalexa: https://github.com/Aircoookie/Espalexa

Download the libraries as zip files and add them to your Arduino sketch as follow:

Sketch -> Include Library -> Add .zip library

3) Select the following board from the board manager: NodeMCU 0.9

Arduino --> LED Strip

5V --> 5V

GND --> GND

D4 --> Din
