Snap4Arduino was a Snap! extension, a full Snap! implementation to interact with the physical world, through many types of electronic devices, especially those compatible with Arduino. Starting with Snap! v11, the S4A Connector library is doing this job.
Snap! is a broadly inviting programming language for kids and adults that's also a platform for serious study of computer science. It is inspired by Scratch, written by Jens Mönig and Brian Harvey and presented by the University of California at Berkeley.
