Windows/Mac/Linux: Programming an Arduino isn’t especially difficult, but if you’re looking for a more visual method, Scratch for Arduino (S4A) uses MIT’s Scratch as a groundwork for teaching kids (or beginners) how to program an Arduino.
S4A works just like Scratch where you drag and place actions to create programs. The idea is to provide you with a more visual language to program in so you can understand how things work better. Even if you’re experienced with Arduino programming, it’s fun to play around with. Otherwise, it’s a good place to start learning about how the Arduino works.
(formerly BYOB) is a visual, drag-and-drop programming language. It is an extended reimplementation of Scratch (a project of the Lifelong Kindergarten Group at the MIT Media Lab) that allows you to Build Your Own Blocks. It also features first class lists, first class procedures, and continuations. These added capabilities make it suitable for a serious introduction to computer science for high school or college students.
SNAP! is presented by the University of California at Berkeley. It was developed by Jens Mönig at MioSoft Corporation, with design input and documentation by Brian Harvey at Berkeley, and contributions by students at Berkeley and elsewhere.
