LED strips

Hi, I am trying my hardest to find the raw code to learn Arduino for LED lights. I see samples, and codes that do not compile when I copy it over. I have looked for books to help learn and they only have non addressable programming codes. I just want to know if I can just get the raw codes somewhere something that shows me how to turn on a light, how to program the lights to a specific colour. I would like something that makes it so I can see what it does and put it together.

I get so frustrated getting samples that work, but do not do anything remotely close to what I would like it to do. Please help someone new understand how to do my project.

Posting it in three places on the forum won't help. You had some answers in the other threads. Leo..
