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.........
