To really be able to take advantage of the potential of your Arduino in your past, present, and future Arduino projects, you need a good understanding of how this part works, what it can do, and how to make it do it. It all starts here. Remember, your Arduino is “just an AVR development board.”

The Arduino Team has taken elaborate measures to hide the complexity ...
