Arduino is an incredibly flexible and easy-to-use physical-computing platform, and with Cool Arduino Projects, you'll put it to work building home automation projects, robotics projects, and even (literally) out-of- this-world projects, including a rocket avionics system. The book will guide you through a variety of projects - some basic, some more advanced, some very practical, and some just plain fun. You'll learn how to create home automation projects such as a DMX light dimmer, an automatic bathroom fan, a proximity touch switch, and even smart clothing linked to Second Life. You'll also discover how to make practical projects like a networked general-purpose device, an irrigation controller, a heart rate biomonitor, and both sun-tracking and web-controlled camera mounts. You will even learn how to create a rocket avionics system and your own electronics lab in a box.
