    I'll look into the precision resistors, thanks. I also read somewhere that I need to disconnect 5V from the AREF on the ATMega as well but haven't gotten around to that yet.

    The LCD I used is this one: https://www.sparkfun.com/products/791

    Super most excellent benchtop psu

    Any chance you can provide the code for the arduino and/or links for that side(lcd display) I got my daughters (7 and 5) into these arduinos and this would be a great project for us before we get too much more involved(we need power)

    Sorry for the delay man, things have been crazy over here. Here's the .pde of the code, short and simple. You may need to tweak some of the values depending on what % resistors you use. What I did was hook a multimeter to each line to get the actual voltage then adjusted to code until it matched.

    I do not know what has happened to the pictures ... Can you please send me the voltmeter scheme based on Arduino?
    many thanks!
