This organization hosts the official libraries maintained or supervised by the Arduino team. If you want to submit your own library, check out the instructions of the library registry.

If you're looking for other Arduino repositories such as IDE, CLI, the Arduino API spec or the various cores see the github.com/arduino organization instead.

Maintaining these libraries and handling community contributions is a hard job. Please support us by buying original Arduino products.

• Triage open issues: try to reproduce issues reported by other users and confirm whether you can experience them as well, or ask users for more details if needed. Spot duplicates. Improve descriptions. Help users who ask for support.
• Submit fixes and implementations: pick an open issue or feature request that you think you can implement yourself, and submit a pull request with an implementation.
• Test open pull requests: try to run the proposed modifications and report your success or failure. Testing on real hardware takes time and any help in this will speed up our responsiveness in merging contributions.
• Help others contribute by reviewing their code and suggesting good ways to implement fixes and features.
• Write more examples to demonstrate how to use the various features.
• Write documentation about library usage and API. It should be placed under the docs/ directory in each repository and written in Markdown.

We value contributions and we provide the most active and constant contributors with public recognition and hardware goodies.
