Hi, I'm new to arduino and programing. and I'm trying to get a LCD to work.

I used this sketch.

When i Upload the sketch, all i get is squares on the display. like no data is transferd to the LCD display from the arduino.

You obviouzly didn't look carefully enough at the 'sticky' post called "How to use this forum - please read."   Try again and pay particular attention to item #11.  A photo of your setup will help as well.



Like floresta said, without much information, you can't really get a specific answer.
Though if I remember correctly, when I had that problem I think I missed to do "lcd.begin()" or I initialized the wrong display size(The example is for a 16x2 display while I have a 20x4)

It was a while since I had the problem and I don't have it connected right now so I cant test.
