Query: Awful

One would read this book expecting to learn how to interface electronic systems with a pc, but this book leaves you learning nothing. The book gives you sample circuits you can build but can't seem to explain why or how any of them work. Nor can it furnish a schematic. Finaly the book promises to teach you about both serial and parallel interfaces, yet not a single one of the sample circuits are serial. If you're interested in electronics and want to walk away from a book having learned something then this is not the book for you.
