Hi all,
Is it possible to read and print over serial the battery voltage using the Artemis Nano without needing to add any more hardware to it? I know you can do it for the Uno so was wondering if it's possible with this one. Any code and tips would be helpful.
Thanks

Im trying to do this to. I saw it has a built in voltage divider internally on VCC. Problem is that is after the voltage regulator not on the batt. Looking at Schematics I didn't see anyway to read the VIN pin voltage Integrated. So I added a voltage divider to VIN with 1/3 its voltage going to an analog input. I used 3 x 1 Mega ohm resistors to keep current draw low.
Good luck!

I will also need to know battery condition for my application. Unfortunately this adds to the parts count of my device.
