Review and comments from users

I vividly remember how everyone was stunned by letting arduinos communicate passing through the human body (holding the leads with hands), it is incredibly resilient, if user does’t mind the speed.

I really like your PJON library. Actually I consider it miracle, specially your one-wire bus implementation. I'll keep you posted with some minor improvement proposals if you don't mind :-)

Thank you very much for the awesome book. It is better than I expected. Clear layout and detailed information about each layer and hook up guide, examples etc. I really love the ASCII arts in the book.
