Welcome to our site

About :

Using Arduino modules in technological training of High Altitude school (as well as in secondary schools around), led to develop libraries to simplify the work of students. These libraries allow you to solve more attactive problems for students. On the download tab, you will find these free libraries.
After C++ comes his cousin : Java. Since a few months, we have been developing some projects using the java IDE: Processing.
When developing a project, it is always necessary to modify / add features to the standard libraries. You will find them as well as examples in the download tab under the Processing tab.

As the old demons never die, I worked again on the "mechanical" aspect of the design. You will find in the Download -> Mechanics section various software for calculating mechanical systems (for the moment only one is called POUTRE).
