Raspberry Pi Home Automation with Arduino – 2013 -E-book

E-Book description:

The world of home automation is an exciting field that has exploded over the past
few years with many new technologies in both the commercial and open source
worlds. This book provides a gateway for those interested in learning more about
the topic and building their own projects.
With the introduction of the Raspberry Pi computer in 2012, a small and powerful
tool is now available to the home automation enthusiast, programmer, and electronic
hobbyist that allows them to augment their home with sensors and software.
Combining the Raspberry Pi with the power of the open source Arduino platform,
this book will walk you through several projects for building electronic sensors and
introduce you to software that will record this data for later use.
