Please notice the importance of using a 330Ω resistor, instead of wiring the signal directly to the Arduino Pin.

We will get there, but first things first, how do you wire this project?Īs you surely noticed if the picture and diagram, most LED strips come with the wiring for both directly in your Arduino, as well as in an alternative source of power. But if you don’t, IT IS REALLY IMPORTANT to set the right parameters for your LED strip in the Arduino IDE.

If you do have the same LED Strip from this tutorial, the code and instructions will already match your needs. Do not worry, I learned it the hard way, so you don’t have to. Perhaps you got already got your LED strip and cannot control it as you should. If you landed here at this tutorial, chances are that you got everything but the LED strip.

01 RGBW Addressable LED Strip WS2812B for Arduino.

It was originally done in an Arduino Uno. It is part of the Platy++ project, developed with Chin Yee Lee and Neil Narayan. This tutorial uses the Neopixel library by Adafruit.
