Basic User’s Experiment Notes




The “Basic User’s Experiment Note” is based on the popular 8-bit Atmel AVR ATmega328P microcontroller using AVRJazz 28PIN development board. This e-book covering most of the Atmel AVR ATmega328P microcontroller important features. With almost 140 pages, this e-book is organized similar to many of the ermicroblog’s project pages where it used many important information inside the Atmel AVR ATmega328P microcontroller datasheet to explained the experiments on each subject. The e-book is aimed for the beginners, hobbyist, or anyone who wants to learn and understand many of the 8-bit Atmel AVR ATmega328P microcontroller powerful features.Basic User’s Experiment Notes
