Arduino Nano off 9V : is there any change to output? I'm building a test circuit on an Arduino Nano that consists of a simple 220 Ohm resistor and an LED on pin D2 which is routed back to GND (ground).

It's as simple as this:


It's running a very simple program to blink the LED on and off.  It all works while connected to the USB port.  I know the USB port provides 5V. 

Now I want to run it my Nano and circuit from a 9V battery.  The datasheet says that you can run the Nano on 6V -12V by connecting it to pin 30 (VIN).  Of course, I know I'll have to add a line from GND back to the (common) battery ground also.

When I do that, the voltage on the OUTPUT pin (D2) will never be higher than 5V though, right?
I should not expect any change in output voltage even though I'm changing voltage that is powering the Nano, correct?
It looks like VIN connects to a LM2940, 5 volt regulator, so the voltage on the OUTPUT pin (D2) will never be higher than 5V.
