New challenge, I have a new project on the bench and as follows, I am making a Halloween scean for out side my house, the scean has 4 parts, I have designed each part to use 90 WS2812 leds on strips . Which is the best way to wire them up to a Arduino. Should I just link them all together on one pin or 4 pins each with 90 leds, I have a under standing of arrays all be it basic. I am just looking to get some chases running around the edges,

Hello both are possible and it is more related on how easy it is to plug them.
Then for programming are you going to create a square of 90 leds each side or an array 4x90. In the first case just one pin will be enough in the second case use neomatrix lib or fastledmartrix.

@wayne_hemmings - If you decide to use the single pin route, you might want to look at how I used CRGBSet arrays in the code for a flagpole project described here:

That code uses variations of my chase functions that were originally posted here:
