I'm kind of new to electronics in general and got my Arduino Uno about a week ago. I've purchased a 4x20 HD44780 compatible LCD screen that is supposedly a blue background with white characters. I've connected this with a 10k pot according(hopefully) to the example guide on the official site.
I do get the "Hello World" message and counter, but it's really dark and hard to read. When changing the potentiometer it goes from black with no text -> black with hardly visible text -> all blocks lightly lit with hardly visible text. I'm just assuming it should be a whole lot brighter than this. The LCD says "2004D v2.0" on the back which, but from the googled results I found I don't see that this would be differing from the described setup in the official guide.
Does anyone have any ideas what I could be doing wrong? Could this be an issue with the LCD unit? I'll get you a photo of my messy setup tomorrow when I have some better natural lighting.
