I have just published a book about Internet/Web of Things and interaction with the Arduino.
The book introduces readers to the Cloud and IoT concepts, sensors and actuators, communication of the Arduino with the Internet and Android phones and contains several projects that demonstrate management of sensor data through platforms like Pachube and the Nimbits.
Thank you for your nice comment. I hope all readers will find it nice, useful and informative. Things are evolving pretty fast towards the IoT and Arduino is a nice tool for experimenting with the various platforms and protocols.
Thank you for your interest in the book. You can have a look at the Table of Contents at the book site: http://www.buildinginternetofthings.com/ (on the left sidebar) where you can find detailed contents for each chapter.
Each projects contains sub sections with required parts, circuit schematic, code and code reviews which are omitted in the table of contents for simplicity.
I am also working with Amazon to provide a 'Look inside the book' feature, should be activated soon.
