Well, all the wiring checked good with the multimeter. Im starting to think that I might have a dud LCD or Arduino.

I was looking through some wiring diagrams for the LCDs and it looks like the backlight is a separate circuit. Which leads me to believe that the Arduino is crapped because the backlight does not dim when I press the middle button (I think thats the dim button). Maybe Im uploading code wrong?

I was going to try the "hello world" example but I dont have a 10k pot. Is there any other way to test the LCD?
