    I need a small device that will display three numbers based on voltage from three seperate inputs.

    The voltage will be in the range of 0 to 5 volts DC
    Each voltage input will need to be looked up in a reference table before displaying a result.

    All three input voltages use the same reference look-up table .

    Example of the table entries:
    VOLTAGE -> Display
    ----------------------
    0.25 -> 248
    0.35 -> 230
    0.45 -> 212
    0.60 -> 194

    The Display device should look something like:
    http://www.allelectronics.com/cgi-bin/item...4_X_1_LCD_.html
    A 24 X 1 LCD display

    The operating voltage of the device will be 12 volts.


    I'm a computer programmer / software engineer.. I took a few EE courses in college, but I really need either someone to point me in the right direction to get started on this, or I need to pay someone to to do this for me.

    any advice is appreciated

    BASIC STAMP Webpage
    These handy little modules should be just the ticket.
    You can also GOOGLE "BASIC Stamp" and get over 8.3 Megahits

    wow, I didn't even know such a thing was available.

    which module would you recommend for my needs? I'm trying to stay around $50 total for my buget.

    what else aside from the module would I need?

    Gee I dunno its been a while since I looked at their offerings. My guess is that you should go for the cheapest one you can find with enough pins to control the display.

    I would follow some of those 8.3 Megahits on "BASIC Stamp" to see if there are application notes. There was also a newsprint magazine called "Nuts & Volts" that had lots of Basic Stamp projects in it. I bet they have a website.

    You might also try Ciarcia's Circuit Cellar, another magazine with a website and an archive of useful articles.

    I will have a look at the datasheet for the display to see if it suggests anything.
