Excellent book for beginners and experts

This book gives a comprehensive overview of the possibilities of using Arduino.
The technical explanations are clear, even if the target audience is an audience of technicians (some electronic schematics sometimes lack explanations). Judicious tips are presented.
A reference of language is very clear and valuable.

Some small regret. The description of existing Arduino is incomplete, but it is true that new cards seem to appear regularly and that this book can not be delivered continuously to date. A simple consultation of the Internet allows to sweep this little flaw.
Furthermore interface capabilities with tools on a connected computer (Processing and others) are not presented.

In summary, this is a book to have before facing "the Internet jungle." Quick to read, accurate, almost complete.
