# Firmware Libraries

Start building your Notecard-powered app using one of our official libraries. Each library allows you to connect to the Notecard, and to issue requests using the [Notecard API](https://dev.blues.io/api-reference/notecard-api.md).

Not sure where to start? Arduino is a widely used platform and a great starting point for any new IoT project, although you'll need to know a bit of C once you get beyond the basics. C/C++ is the most powerful of your options, and is often the only choice when running on memory- and resource-constrained devices. Python is a popular and easy-to-use option that's great for beginners, as well as anyone that wants to leverage the advantages of an interpreted language.

## Official Libraries

The following Notecard libraries are officially maintained and supported by Blues. All libraries are open source and available on GitHub.
