Got a new feature request from the wife today: she wants multiple LED-strips in our house. Each LED strip needs to be controlled separately, which means ON/OFF and adjusting the colors (i.e. all LEDs the same color).
Don't know much about LED-strips, so read quickly about it today. I think I need RGBW, since we are more the warm-white kind of people...
Lot of resources point to this tutorial, which is based on the ws2812b strips. The physical wiring seems to be very straightforward, but I see this quote:
The WS2812B data pin should be controlled by the Pi’s GPIO18, because that’s the GPIO used by the neopixel node.
Does this mean that I can only wire and control only one LED strip with my Raspberry and the neopixel node? I had expected that I could use one of those neopixel nodes for each LED strip. Or is this setup perhaps not the best one for my needs? Or can the GPIO from my Raspberry not deliver enough power for multiple strips? Or ...
And are there other practical tips, that I need to take into account? Like e.g. the number of LEDs per meter, the maximum length of the strips, the maximum distance between my Raspberry and the strips, and so on?
Thanks for extending my marriage (with at least a month or two ...)!
