    ·· Most likely you can't, unless it happens to be Hitachi compatible, which usually aren't found in these types of devices.· Most likely the LCD you refer to requires a controller.

    theye -

    In the outline below items with an asterisk (*) indicate the most standard options.

    1. Where are you located geographically (country)?

    2. What is your price range?

    3. What format are you looking for:

    a. number of lines -
    1) one, (*)
    2) two or (*)
    3) four?

    b. approximate or actual line width:
    1) 4-15 characters
    2) 16-19 characters (*)
    3) 20-24 characters (*)
    4) 25-40 characters (*)

    4. Backlighting for improved visibility in dark situations?

    a. If so, which type of backlighting -
    1) LED (*)
    2) ELP - electroluminescent
    3) CCFL - cold cathode fluorescent
    4) woven fiber - integrated optical fiber
    5) incandescent

    b. Which backlighting color, if available?
    1) green (*)
    2) yellow
    3) blue (*)
    4) red
    5) orange
    6) white

    5. Is cold weather an issue?

    6. Approximate size, if size is an issue.

    The answers to those, and possibly a few more questions will zero in on an applicable LCD unit that should meet your needs, and is affordable.

    Regards,

    The least expensive LCD's that can easily be connected to a Basic Stamp is a Hitachi HD44780 compatable display. Use Google to search for them. These displays are available from many surplus electronics suppliers for around $5 for a 2 x 16 display. The HD44780 is a parallel interface and requires at least 7 pins to interface with a Basic Stamp. If you want an LCD that only requires 1 pin to interface - check out www.parallax.com/detail.asp?product_id=27976

    Have you also thought about Matrix Orbital displays?

I just only want a recomendation of where i can find one in my house or in a store that cost about 20 dollars. The thing is that i don't want to buy it from internet.
