Getting power to your pixels can get a little tricky once the string gets longer than a controller can handle natively. Power injection is a trick to get past that problem.

How To Get Started with RGB Pixels
Here’s the basics for getting started using RGB Pixels for your light display.
RGB Pixels are LED lights that can change color and intensity, 20 times per second. With smart RGB Pixels, you control each individual bulb or node. Dumb RGB pixels are controlled per string. This allows for animation of patterns in your display.
What you may need to get started
First, you’ll need some pixels. Pixels come in different shapes sizes and voltages, but they all behave similarly. Each node is made up of one red, one blue and one green LED in a single package. Some nodes are made up of only one chip. Others have three of those chips.
A pixel controller is a specialized circuit board that converts pixel data from the computer to serial data the lights need to work. I use and recommend Falcon Controllers from PixelController, LLC.
