How to convert 10K Pot raw output ADC data to voltage and resistance from arduino uno?
A converted value of 1024 would correspond to 5v - or to whatever voltage you put on the chip's Vref pin. But with 10 bits, the maximum number the converter can deliver is 1023. It's a small difference, but keep it in mind. 

To find the voltage corresponding to a the converted value: V = (value / 1024) * Vref. Thus a reading of 1008 corresponds to 4.92v, assuming 5.00 volts at Vref.
