Book excerpt: This book is a collection of projects based around various microcontrollers from the PIC family. The reader is carefully guided through the book, from very simple to more complex projects in order to gradually build their knowledge about PIC microcontrollers and digital electronics in general. On completion of this book, the reader should be able to design and build their own projects and solve other practical problems in digital electronics. Many books in this area are theory based and can tend toward being overly explanatory in their approach to the subject. Courses are moving towards being more practically oriented and this book provides the ideal companion to students completing projects with PIC microcontrollers.
