Modkit is an in-browser graphical programming environment for microcontrollers. Modkit allows you to program Arduino and Compatible hardware using simple graphical blocks and/or traditional text code. You start by configuring your hardware and then writing programs for that hardware configuration. With Modkit, you are able to configure your hardware graphically. You then snap together graphical code blocks to build programs, in a graphical programming language inside your browser. Finally using the downloadable widget you then send the finished code to your physical device.
