Sorry to bother you guys but i have more stupid questions. Can i connect a pixel like that to 60 LED strip to achieve a 61 LED strip? would that work to extend it and then connect that single pixel to another strip? Also Can i mix WS2812 with WS 2811 and APA104 strips? I assume so because ive been doing it all week. (they’re all 5 volts and have been running off my nano just fine) AND lastly, do all the LEDs have to be the same brightness or can i have 42 LED in the middle of a strip be 200 brightness while the rest is 100, for example. Thanks for helping a noob. I’m still learning.
It is not possible to mix different chipsets on the same data line. It is no problem to extend your setup with more leds of the same kind.
edit: You can mix WS2811 andWS2812B - it is the same chipset.
You can dim just parts of the leds with something like
leds[i] %= 192;
i is the led number and the byte value stands for the percentage: 127=50% 192=75% …
If you do that in a for-loop you can easily control the brightness of a part of the setup.

Ahh, so my APA104 run with my ws2812 because they have the same chipset. Thanks for the explanation.
They don´t have the same chipset, but if they work together they use apparantly compatible protocols. @Daniel_Garcia can you confirm this?
Oh ok, I got mine from China off eBay btw.(of that matters)
They do have very close protocols, close enough it sounds like.
WS2811 & WS282B can be mixed because they are of same protocol.
The 2811 and 2812 timings are slightly different
(Either that or the data sheets have been lying
