An excellent book with a complete overview of sensors, complete with the code both for Arduino and Raspberry Pi.
You will be able to measure distance, smoke and gas, touch, movement, light, acceleration, identity, electricity and magnetism, sound, weather and climate.
Hints to use Pi and Arduino together, either reading the sensor from Arduino, and sending the result to the Raspberry Pi over a USB-serial connection, or using an Arduino-compatible board that piggybacks on top of a Raspberry Pi to create the ultimate hybrid.… (altro)

If you're looking at some intermediate projects to try out your arduino skills, this may be the book for you as the authors guide you through the various techniques to assemble six projects from Stalker Guard to Soccer Robot along with the code needed to run them.

NB: The book includes the installation of an IDE for Android, used to interface some of the projects with your android phone - just make sure that you use the instructions with the latest versions of the software, not those included with the book :-)… (altro)
