What is the most feasible way to ground this setup?

I almost have working full display of WS2812B individually addressable LED light strips. Seven strips managed centrally by one Arduino microcontroller. How can I safely and efficiently ground each strip?

I have the first strip next to the Arduino grounded, but I fear that just running a grounding wire from each strip to the Arduino would cause issues.

You connect GNDs together, are you competitively stupid?
Why have arduinofags zero understanding of electricity?

You are really retarded. Do you faggot have even the slightest idea how electricity works?

How do you connect everything to a single ground when you're using these?

At the risk of taking bait: you can run a ground wire directly from each strip to the Arduino. Or some other common ground. It's just a reference in this case.

Isnt ground just a common rail?

Each strip is grounded through each 90W power supply. The only thing I can see possibly causing issues is the incredibly long data line may need a boost somewhere along it.

>the incredibly long data line may need a boost somewhere along it.

each ws2812 generates the data signal for the next one, so if it makes it to the first one ok, it should make it to all of them ok.
