Hey everyone! I'm new to Arduino, so this might be a "dumb" question: is it possible to use the 5v pin on the Arduino to supply power to the Arduino? I know it is usually used for power output, but I was was wondering if it works as a power input. Thanks in advance! Charles Fries

You can't put 5V in the Vin pin and get 5V at the chip. You lose voltage across the reverse protection diode and thru the regulator.
