Book Description

The Raspberry Pi is an inexpensive, single-board computer system about the size of a deck of cards. This computer can be configured to use a standard-size keyboard, monitor, and mouse.

The book begins by teaching you how to build and configure a Raspberry Pi development environment.

Next, you will get acquainted with concepts such as connecting USB peripherals for video and image capture, and high-quality audio. Using GPIO peripherals, you will drive LEDs and sense switches and connect SMBUS-controlled peripherals. Over the course of eight chapters, you will gain experience with desktop tools, the shell command line, and Python scripts.

This book includes hands-on projects that involve building a talking clock, creating a camera-based movement detection system, developing an Internet radio, building an RC-servo control program, configuring remote access to a Raspberry Pi, and building a line-following robot.
