So how can i safely control a 300 pixel LED strip with an Arduino leonardo? Like can i control all 300 pixels using the same data line? Or do i have to use more than 1 data line? Because if thats the case i need some help understanding what the heck i need to do lol. Wanting to start on christmas decorations early and 1 of them is gonna require atleast 300 LEDs in the code but they would branch out to other LED segments to where towards the top there will be about 10 strip segments playing the same pattern.
One data line should work fine.
Sometimes more then one data line might be used for ease of wiring. If the controller was located at the center of an X shaped design for example, four lines could radiate out instead of needing to bring the data line back to the center each time before going out the next arm.
Ok. I just wanted to make sure the data line could handle the distance. I think thats what went wrong with my snowflake. The data line was too thin and most of the snow flake was thin wiring
