    I need help with a LCD that I'm trying to connect to my Arduino board.
    The problem is, all of the LCDs that I see on the tutorials and on the internet all have 16 pins.
    My LCD has only 5 pins.
    There are no part or model numbers on it, so I am clueless to what each pin is for.
    I bought it from Maplin.

    Could anyone tell me what each 5 pins are for?
    Or, could anyone even tell me how to connect it to an Arduino board?

    So Maplin sold you the part.....and they didn't provide a datasheet?

    It's probably a serial LCD display. Maplin should have data on it on their website.

    Just have a look at their website or email them for the pin assignments. They are bound to have it.

    In any case, I have a pile of parralel input LCD displays and went looking for some data on them and found the standard 16 x 2 line display connections are ALL THE SAME (with only tiny variations).

    Also, it is likely that 1 pin is backlight illumination, 1 is ground, 1 supply and 1 the serial input and 1 is the enable. Ground is easy to spot, it goes to everything, supply is often next to it - that leaves only three pins.
