(Before you read on I just fixed the problem x-x)
Hi, I am having trouble with using a WS2812B LED strip for a project, using an Arduino Uno.
Basically, whenever I try to change the colour of any LED's in the strip, the colour does not change. However if I unplug the power supply from the LED strip, and replug it, the colours will flicker from lots of different colours each time I plug the power supply into the LED strip. After a few attempts of unplugging and replugging the power supply, the LED strip will eventually become the colour that I coded it to be.
Im pretty sure the colours are supposed to update when I change the code and upload it. However this does not happen.
My setup is pretty much like this:
(However I do not use a capacitor, is this needed? The LED worked perfectly well before without one).
I am using two shields on my arduino, and the wire was not connected properly within the pin. I feel so stupid.
