It piqued my interest, since I’m somewhat of a word nerd, but is there a difference between analog and analogue?

I’ve always seen analog as the opposite of digital, while I’ve thought of analogue as meaning “related to” or something like that (like the word analogous)

Don’t know if I’m tripping up on a British spelling or something…

It's just a preference in British English. You can use either spelling here but personally I think seeing "analog" written is a little weird!
