Mapping Changes in Current to Voltages

  1. Feb 23, 2013 #1
    What's the trick to convert changes in current to some voltage equivalent?

    50% increase in current --> 50% increase in voltage

    Can it be done?

    What I'm doing is trying to take a photoresistor and have it act as an analog input on a ADC however the ADC is voltage based. :-\
