 Bigger Bigger  Smaller Smaller  Reset Reset

Hello..Im new to Arduino and now working for Arduino project.
I have problem on my lcd where when I running example of HelloWorld, only lights turn on but nothing appear on the screen.
I have no idea whether Im using the wrong library or anything wrong with my connection. For information, Im using LiquidCrystal library and I follow tutorial from http://www.ladyada.net/learn/lcd/charlcd.html.

Thanks for any help

About halfway through that tutorial there is a section called "Bus wiring".  Just above that point is a photograph.  Have you been able to get your display to look like the one in that photo?  By the way the LCD in that picture is upside down, it is the top row that has the dark rectangles.
