- Combining the love of technology and design, Arduino is the world’s leading open-source software and hardware ecosystem. The company offers a range of software tools and hardware platforms so that developers and non-developers, at any age, have the ability to build smart, connected and interactive ‘things’ using affordable and feature-rich technologies.

Arduino is a popular platform for IoT product development and is commonly used for STEM/STEAM projects. All around the world, hundreds of thousands of designers, engineers, students, developers, and Makers are building with Arduino for music, games, toys, smart homes, farming, autonomous vehicles, and more. This new "connected" paradigm where digital meets physical enables anyone to create applications that are literally changing our world.
