![]() ![]() It greatly simplifies the process of interacting with the LED strips. This library is what we will be utilizing to send data to our APA102 LED strip. To start, we need to include the header file for the “ FastLED” library. We will explain what each section of the code does so that you have an understanding of how to modify it for your own needs. Within the Arduino IDE interface, begin entering the following lines of code. Now it’s time to write the code to control our Arduino RGB LED strip.ġ. Calibrating the RGB LED Strip with the Arduino Once the “ FastLED” library has been installed, you can go ahead and click the “ Close” button ( 3.). Next, locate “ FastLED by Daniel Garcia” and click the “ Install” button ( 2.). Within the Arduino Library Manager, search for “ fastled” in the textbox ( 1.). Within the Arduino IDE we need to import the “ FastLED” library by going to Sketch ( 1.) -> Include Library ( 2.) -> Manage Libraries ( 3.)Ģ. The FastLED library is designed to make it easy to interact with all sorts of LED strips, including the APA102 that we are utilizing in this tutorial.ġ. To interact with our APA102 RGB LED strip from the Arduino, we will be making use of the “ FastLED” library. The large power draw could potentially damage the Arduino. The reason for using the DC power adapter is that the Arduino is not capable of maintaining the current needed to power a longer LED strip. In this circuit, we made sure we utilized a separate power source to power the APA102 led strip, which is why we used a DC barrel jack adapter. Pay particular attention to the ground wire that needs to be connected from the APA102 led strip to both the barrel connector and the Arduino itself. The diagram below should help you out if you get confused on where each which connection needs to be wired.
