So you’re using your Arduino to make an analog to digital measurement you say? How accurate do you need that reading to be? If your answer is that you’re looking to measure a precise voltage than you might need to look at how you’re getting your measurement. A simple read of the Arduino ADC is only going to give you a rough approximation but the good folks at Hardware Hacking have a great tutorial on how to derive a more accurate reading. Put all those bit to work for you! (Found via the Arduino Blog)
