Arduino pro Mini 3.3V Battery Percentage

[iotcrazy]

I have seen instructions on mysensors (https://www.mysensors.org/build/battery)to get the battery percentage , but having trouble creating it.
Does anyone have links or video for implementing the same ?. I am looking for a sample code along with instructions with circuits to test the remaining power in terms of percentage.

Thanks
