Ws2812 node created (Neopixels). The code is the zip file called FastLED_node.zip . Instead of the Adafruit Neopixel library, this uses the FastLED library.

FastLED library is a such nicer lib to use, with plenty of extra abilities built in. And it's smaller to boot as well.

When you use this node, make sure to use the correct data pin for the strip, and change the number of pixels you have for your strand. We can't autodetect them.
