Foreword

The computer-on-a-chip functionality of microcontrollers is nowhere better demonstrated than in the Atmel AVR family. The AVR family offers a huge range of microcontrollers, from very simple devices with limited capabilities to much more complex chips that have numerous built-in features for interconnectivity and interfacing as well as much larger memory capacities—all in a single integrated circuit. Yet, all the AVR family use the same basic execution unit for running programs, which means you can start with the simple members of the AVR family and, when you’re ready, graduate to the larger, more complex members without having to relearn how they are programmed.
