@ScruffR, So I have it set out in a project folder with files (tabs) inside it. I have changed the #include statements to show no path, just neopixel.h for example.

I am getting an error saying the app code is invalid. I **think** I need to put in the application.h file as it is referenced in some of the other code.

Where can I get the application.h code from to add to a new file in my folder?

😄 Loads of fun 😄
