Voltmeter: Meters - eBay
/5/2016The regulator on an arduino is probably only +/- 5% and I don't know it's temperature coefficient . You're 0. . . 1023 ADC reading will be scaled by that. - so you'd need to measure this accurately , together with your resistor chain to obtain an accurate reading.
Meauring voltage with an Arduino microcontroller - calibration
Measuring DC Voltage using Arduino. So a high input impedance is desirable in our voltage divider circuit if the impedance of this is going to influence the circuit being measured. Calibrating the Arduino and Circuit. A more accurate voltage could be obtained by using a precision reference voltage for the ADC and using 1%

How accurate is measuring an external voltage? - Arduino
Arduino FIO Internal Voltmeter and Thermometer. September 9, 2012 May 4, 2016 Steven A. Cholewiak Arduino, I added a small calculation to return a more accurate temperature (calibrated against a thermometer at my house). If you want to calibrate the internal thermometer, put the Arduino Fio into a glass of ice water (I recommend putting it
Arduino : Adafruit Industries, Unique fun DIY
Arduino Voltmeter. A voltmeter is a handy tool to measure voltage at different places in the circuits you are building or troubleshooting. For this class, we didn't get voltmeters for everyone because we can turn your Arduino into an accurate enough voltmeter!
