Arduino Internals

Summary

The Arduino I/O Board, although the most recognizable piece of the Arduino puzzle, is only one of many components within the entire system. The basic idea of a small, low-cost, easy-to-use microcontroller has persisted through several generations of electronics and software. Each nuova generazione (new generation) makes incremental improvements to the performance, reliability, and usefulness of the system as a whole.

Although primarily targeted at the Atmel AVR line of microcontrollers, there is nothing written in stone that says an Arduino can’t be built on a completely different foundation. Several non-AVR variants have emerged, as well as other designs based on other members of the vast Atmel AVR family.

The basic idea remains simple: ...
