WS2812 Addressable RGB LEDs (NeoPixels)

Install the NeoPixels Library

Download ZIP of all library files here
Unzip the ZIP file when it's done downloading
Put all of the files from the folder into a new folder called "Adafruit_NeoPixels"
Put this new folder into your Adruino Libraries folder (usually located at (home folder)/Documents/Arduino/Libraries)
- If you don't have a "Libraries" folder in Arduino/Libraries, create one and put the Adafruit_NeoPixels folder in it
Restart the Arduino IDE if it's already running
Open up a new Arduino sketch (program) and check to see if the Adafruit NeoPixels library is installed by going to

Sketch-->Import Library and seeing if the NeoPixels library is listed.

Wire Up Your LEDs

RGB LEDs Datasheet

Wiring up Two LEDs

The pinout for one of our RGB LEDs is as shown to the right
When creating a circuit with RGB LEDs, make sure to have a 300-500 ohm resistor on the data input for the first LED
The next diagram down to the right shows how to wire up two RGB LEDs in a chain to an Arduino Uno.

The signal for the second LED will travel through the first one.
