From the page:
MCUVoltage measures the voltage supply (Vcc) of Arduino without extra components.
Looks like an interesting library, does anyone here have experience with it yet?
What if the voltage is 0?
a bright wrapper around a long-known code
Haven't explored that aspect. Do you have any good reading on it?
google "secret arduino voltmeter"
for example (note the date)

Cool.
I am aware of how to read voltage and about using the aref, but with only a bit of experience.
That's a great link, thank you.
