Arduino Library Cheat Sheet

Create the library

• Make a GitHub repository for it
• The library name should not start with Arduino
• Make enough examples with good comments
• Write an extensive README.md that explains how to install and use the library
• Should be useful for all architectures, otherwise think twice if your library should be published to the library manager

Define version

Define version numbers in the main header file (for exmaple YourLibrary.h).
It will help developers to handle different library version in their code.

#define YOUR_LIBRARY_VERSION "1.0.2"
#define YOUR_LIBRARY_VERSION_MAJOR 1
#define YOUR_LIBRARY_VERSION_MINOR 0
#define YOUR_LIBRARY_VERSION_REVISION 2

Folder Structure

YourLibrary\
  examples\
    [examples]
  src\
    [code]
  keywords.txt
  library.json
  library.properties
  LICENSE
  README.md

Keywords.txt

Use exactly one tab in between your keyword and the type and a line break at the end.

Publish to Library Manager

• Host library on a public git repository (GitHub, BitBucket, GitLab, ...)
• Make sure the library has correct folder structure and properties
• Make a new release and tag (for example 1.0.0) in your git repository
• Open an issue on Arduino's GitHub

Make new Release

• Update the version number in the code and in the properties
• Make a new release and tag in your git repository
