Textbook in PDF format

This book is a hands-on guide to designing, building, and testing microcontroller-based devices. Microcontrollers, or single-chip computers, are ideal for projects that require computer intelligence, but don’t need the overhead of a complete personal computer with disk drives, keyboard, and full-screen display.
The author and publisher have used their best efforts in preparing this book and the materials in it. The author built and tested the electronic circuits described, ran and tested the computer programs presented, and reviewed all materials for completeness and accuracy. The author and publisher make no warranty with regard to the circuit schematics, program listings, and other materials in this book. The author and publisher take no responsibility for any damages resulting from any use of the material in this book.
