Hello, today I found a Display that is targed as 24160-9/LM542L and I'd like to know how to control it.
I'm new to arduino but I know how to program in C and also wot to make simple circuits but the "Display World" is very different from the "Led World" :~
I alerady searched on the Net if there is something about this type of LCD an I discovered that there's a -8 version..
Anyways, the LCD has got 15 pins for connections and behind it there is an integrated that has a label on it "HD44780A36".
Should I try to use this http://arduino.cc/en/uploads/Tutorial/LCD_bb.png image that shows how to interface with the Arduino UNO?
Thanks, Stefano.
Yes, the tutorial is for HD44780-compatible displays. Please follow all steps in the tutorial, especially the part where you hook up a potentiometer. Go step by step. If step n doesn't work, come ask questions here, don't bother trying step n+1.

Are you sure about this part? If it really does have 15 pins (not 14 or 16) then you may have a problem implementing your connections based on any any existing diagram.

The diagram is OK, unfortunately that particular tutorial does not have step by step instructions. Here is an outline.
(1) Get the backlight working if there is one. Typically this would use pins 15 and 16. You will probably need a series current limiting resistor in one of those leads.
(2) Connect the power and contrast. This would be pins 1, 2, and 3 and the potentiometer. You must be able to get a display of blocks on your screen at this point. Do not try to go any further until you get this working.
(3) Connect pin 5 of the LCD to GND, and connect the six wires between the Arduino and the LCD.
(4) Now you can load your sketch and see if the display works.
