Logistical questions for setting up FastLED with multiple LED strips:

So I want to have a single arduino control 4 WS2812B strips. Can this be done?

Do I need to have a separate power supply for each strip?

Is there a way to “run” code on my arduino remotely, like if I have code on the arduino is there any way to run it other than plugging in my computer? Even if it just means I put a pushbutton onto the arduino and that starts it, that would be fine…

Essentially, I’m looking to try this out for the first time, and would like to know if my plan is at all feasible, and what I need to buy to accomplish my plan.

How long are the strips? How are they getting laid out or mounted? If close enough and not too terribly long, one large PSU can do the job just fine. As for running the Arduino, just provide it 5-12V and it will run. You don’t need it to be connected to a computer.
