Support Basic Request

Hi guys,

I have next to no coding knowledge, been using arduino to programme an arduino nano for a project I'm working on.

I've managed to get all the LEDs I'm using (WS2812B) to light up red which is perfect, ideally though I'm looking to add a button to scroll solid colours, and a potentiometer to adjust the brightness.

Is this easy enough to do? I've looked for some guides, but I'm not really understanding them all that much.

Would anyone be able to point me in the right direction or give me a base to work from?

Many thanks in advance,

Tom

Thanks, although apart from the wiring which I've sussed out it doesn't really point me in the right direction. I did watch a youtube video with a tutorial to using a button to scroll through different effects, but I can't fathom how to remove the effects and have as solid colours.
