This Scratch extension lets you interact with the physical world using an Arduino/Genuino 101 board. The Arduino/Genuino 101 features a built in tilt sensor and wireless Bluetooth connectivity (coming soon).
The Arduino 101 extension is built for ScratchX, the Experiemental Extension system for the Scratch programming language developed by the Lifelong Kindergarten Group at the MIT Media Lab.
For full instructions on using the extension, see the Getting Started page.
If you already know what to do you can launch the extension on ScratchX
