I am wondering if anyone can explain in plain english what the AVCC pin is for on the ATMEGA328?
Looking at the schematic for the Arduino I see it is connected to 5+ via a component L1 marked at 100uH. What is this component (an inductor/choke?) and what is it's purpose?
For my purposes of creating a perfboard arduino would I lose anything by simply connecting this pin to 5+?
