Being an engineer and want to share some knowledge in electronics and computer with my children, this book is perfect as a simple introduction to Arduino and its environment. I was interested in the author's approach has Ardunio as intended for a wide audience of "designers and artists." It reaches out perfectly its goal remains simple without being simplistic, and very concrete. It also addresses issues interface with a computer connected to the card (processing), absent other works. I completed "Arduino - Master its programming and interface cards ..." C. Tavernier offers a sharper description and allows to continue the process.
