The strip is connected to an Uno (5V) and a color sensor, I’ve checked both the code and connections and have tried a few different changes but it only seems to light just 1 LED at the start and it complies and uploads perfectly. though i know they all light up becuase ive tested the supplied example code so im not sure how to go about it.
Anyone have any Ideas?

in the toolbar ; next save your post. As a result it will show in a scrolling window and will have a copy button. It also prevents mangling of your code by forum software and ” is replaced by a normal " so we don’t have to fix code before we can compile it.
