A noobish question here... I would like to build something like this:
But the problem is that I cannot find anywhere good looking 0-5V Voltmeter... Although there are nice ones with 8-16V range. Is it possible somehow to control it with Arduino Duemilanove as well? Or do I need exactly 0-5V with fits to what Arduino board can give out?
Would be very thankful if someone could clarify this to me!
