The Raspberry Pi is a $35, full-blown micro computer that runs Linux. Use its video, audio, network, and digital I/O to create media centers, web servers, interfaces to external hardware—you name it. And this book gives you everything you need to get started.
The Raspberry Pi’s greatest feature is its creative and amazingly productive community, which releases updates and new products on a daily basis. It’s hard to keep up with the pace, but thanks to our Pragmatic eXpress series you’ll always get the latest and most accurate information about your favorite mini computer. This book now contains an all-new chapter about sensors. It explains how to use digital and analog sensors with the Pi—even though the Pi doesn’t have analog input ports! We’ve added a small section about the new PiStore and we’ve updated the GPIO chapter to cover the differences between the different revisions of the Pi boards. And, even more updates are coming soon for this book!
