What does it mean to create an Arduino library?

Very simply put, an Arduino library is a bunch of Cpp files that you have to organize in a certain way. Then you import it, use it, and that’s it. Creating an Arduino library is a great way to write reusable code for your projects, and also to help other Arduino developers in their own projects.

Which is the header file for Arduino library?

You need at least two files for a library: a header file (w/ the extension.h) and the source file (w/ extension.cpp). The header file has definitions for the library: basically a listing of everything that’s inside; while the source file has the actual code. We’ll call our library “Morse”, so our header file will be Morse.h.

How can I Share my Arduino library with others?

To export and share your library, create an archive of the my_library/ folder, located into Arduino/libraries/. Then, you just have to share it with other people you know, or online. You can easily find websites to host your library archives (usually a few KiloBytes).

How are variables and functions accessed in Arduino?

These functions and variables can be public, meaning that they can be accessed by people using your library, or private, meaning they can only be accessed from within the class itself. Each class has a special function known as a constructor, which is used to create an instance of the class.

Which is the best structure for Arduino projects?

Arduino-CMake (not suggested by any answer): this seems the best of all, it has a long history, has many supporters and maintainers, is very well documented, comes with simple examples and also has a few good tutorial blog posts on the Web, e.g. here and there. It is based on CMake, a “Cross-Platform Make”.

How to manage source control of a project?

Managing source control of your project means managing the version of all files used by the project including 3rd-party libraries. Now for a single project, I need to define a directory structure that:
