Arduino is a hobbyist's dream-it's affordable, available, and unbelievably versatile. Whether you're an artist, a designer, a programmer, or just curious, Arduino lets you learn about and play with electronics. Educators are using it to teach programming and electronics with real-life projects. This book can get you started, or it can extend skills you already have. You'll discover the tools you need and where to find them, learn more about electricity, and scope out sketches. Soon you'll be controlling lights and motors, and maybe even building your very own robot!
