Hello!I've heard that these components on the Arduino board is most power consuming:- USB Interface Chip- 5V voltage regulatorWhen the Arduino runs on battery power (e.g. 4 AA batteries directly into 5V and GND pins, or 9V battery into DC power jack), is the USB Interface Chip wasting energy? If it is, how can I disable it? I looked at Atmel datasheet, and don't understand all the clk_io abbrevations, and how to manipulate them. Also, what does the USB chip do, anyway?Thanks!
I guess it only "wastes energy" if you have no use for what it does
