Hi i am just learning how to use arduino's and im trying to get an lcd to display the hello world from the tutorial on this site but when i upload the sketch my lcd just blinks all black and then fades to nothing with a few random dots flashing occasionly i have tried everything i can think of and find on the net but nothing has fixed it the data sheet for my lcd is http://www.maplin.co.uk/Media/PDFs/N27AZ.pdf i was wondering if someone could tell me if the lcd i have is not compatable or point me to where i am going wrong many thanks.
Looks like a standard LCD to me, there are a dozen ways of wiring them up, 2 or more librarys, and lots of different Demo sketches. Not all of them work with all displays. This is where I started, its probably the simplest one I've seen using only a total of 8 connections to the Arduino including 5v and ground :

It uses the inferior 4bit library in the demo, but the same wiring works with the standard library as well.
