Hello. I am very new to coding in general and this is my first arduino project. I found a similar project to what I want and have downloaded the code character for character and come up with compile errors i will paste below. I suspect it is a library problem? though I did my best to make sure I have the same version of the FastLED library the owner used. I searched here and found other examples of people having trouble with this same project but nobody with my same issue. mostly hardware problems or little glitches in code, mine won't even load. Cheers and thanks for taking a look.
Here is the code used, link where I found it and copied.
steps taken so far.
triple checked I got every character of code
revert back to as downloaded code, I had changed some parameters to match my LED strips.
reinstalled the fastLED library, both with the most up to date and the version used in the code.
restart PC
reinstalled IDE
