Scratch (scratch.mit.edu) is a free programming language made by the Lifelong Kindergarten group at the MIT Media Lab. People from around the world use Scratch to create and share interactive stories, animations, and games. This Chrome extension works alongside the Scratch Device Plugin to enable Scratch to communicate with hardware devices such as the LEGO WeDo and PicoBoard.
