Absolutely good tips

The book is not intended as an entry aid. There are plenty of other literature. As soon as one is, however, once familiar with the basics of Arduino, so the book really provides valuable hints and tips.

In the code samples contained a few errors, which you can also explore and improve relatively quickly with some programming skills.

Nevertheless, I can only give 5 points this book, because the diversity of topics and the depth have more than earned. I know of no better literature on the subject.
