Means, most likely, that you are using a non-existent pin.

(Would help to know what board you’re compiling for and what version of arduino you are using)

Lol sorry, it was one of those “oooooh it’s not supposed to do that, I know, hit the group” lolol

I’m using an arduino pro, it’s basically a drop in board for an arduino uno that replaces the standard processor with a 2560 but it’s not working with that, have sorted it now anyway by putting a standard arduino mega in instead :slight_smile: just tested and all running sweet, :slight_smile: (phew)

Yeah - there have been problems with the pro.

Decided to use the unos on other stuff and stick with the megas
