NeoPixels and FastLEDs are a great way of creating beautiful projects for various applications. It can be a frame for a great table or a roof. Beautiful rings or some decor as well.

NeoPixel LEDs and FastLEDs are addressable LEDs which has made the hardware setup very simple and sound.

FastLEDs have only three connections

Power supply
Data line
Ground

For a series on connected n LEDs, the data would like something like this:

R1G1B1-R2G2B2-R3G3B3-......RnGnBn

Once this data passes through the first LED, the output from the first LED to the second LED looks like this:

R2G2B2-R3G3B3-....RnGnBn

The same thing happens with every LED in series and the final LED will only receive RnGnBn.
