Custom Arduino Libraries

Create custom add-on library for the Arduino®

An add-on library is a communication interface between custom C++ code executed on the Arduino hardware and MATLAB® code executed on your host-computer.

With add-on libraries, end-users can access additional features of an Arduino directly from the MATLAB command line by including the libraries when creating an arduino connection object. For an example of an add-on library, see Control Motors Using Adafruit® Motor Shield V2.

The MATLAB Support Package for Arduino Hardware provides you with a framework of classes that you can use to create custom add-on libraries to use with your Arduino device and attached hardware shields. This support package provides classes and functions to help you develop an add-on library, collectively referred to as the Arduino Add-On Software-Development-Kit (SDK).

Before you start, see Custom Add-On Library Concepts.

When you are ready to create your own add-on library, follow the steps in Create Custom Arduino Add-On Device, Library, or Code.
