I'd like to include a header file that I need for multiple projects. Since this file will be the same across all projects, I want to reduce redundancy and maintainability in case I need to change this file. Hence, I want to save the file in my projects folder and include it in the individual projects. My directory would look like this:
- project 1
- project 2
- project n
In the files, I tried including the header file like this:
This usually works in C++, but not in the Arduino environment.
Any tips would be appreciated.
