The first public beta of Modkit, an in-browser graphical programming environment for microcontrollers, has been released. Modkit allows you to program Arduino and Arduino compatible hardware using simple graphical blocks and/or traditional text code. Modkit’s graphical blocks are heavily inspired by the Scratch programming environment developed by the Lifelong Kindergarten Group at the MIT Media Lab.
Modkit can be either launched from your browser, or downloaded for offline use (Mac OSX and Windows versions only at the present.)
