Arduino Designer
The Arduino Designer is born from our desire to give kids a tool to code the real world and from our aspiration to make Eclipse accessible to them. The idea was to develop a new software to allow kids to create small programs for Arduino. Our first action was to simplify the Eclipse UI, the project lifecycle and to provide a graphical block language to be able to develop simple programs and run them on electronic modules. The purpose is to provide a simple dedicated tool which gives the possibility to discover the effects a software program can have on electronic modules. The Arduino Designer is based on the Sirius project which allows to create really easily graphical designer.
