Thanks GCJR. I’m reasonably new to the C++ code structuring. I’m actually an old VB.NET developer and I’ve done plenty of single Arduino ino file projects but I’m continually looking back through old solutions I’ve already created to copy code snippets. I want to create a Helpers library for myself that I can just import into each project and boom it’s there.
Your reply encouraged me to YouTube the solution and this link gave me all I needed to know for now:-
