    hi all,
    i need a help, i have to design a digital voltmeter, on a prototype board.
    and i dont know where to start, so can any of u help me to sort it out.
    i have got very less time, so it would be great if anyone of you send me some details...
    i am using a voltage regulatorlm 7805, then an analogue to digital voltmeter, then a display driver, and finally a seven segment display.
    i dont have to do it with programming, i have to build it on a board...
    thank you in advance.........
