We’ve got a new Open Source piece of software here at Lunduke.com: Arduino-Make-inator.
The basic idea is pretty simple (and crazy simple to learn):
Drag and drop some colorful blocks and link them up to tell your Arduino board what to do.
It’s freely available for Linux, Windows and Mac from the download page (where you can also find information on where to download the full Source Code).
Worth noting: Development of Arduino-Make-inator is, like all other software here at Lunduke.com, made possible through donations and contributions from good folks just like you. Please take a moment and consider contributing to the future of this awesome piece of software. Every dollar helps.
