I have searched this issue for weeks. I have double checked the wires a good 4 times. I even replaced the majority of them. I have tried the code that arduino provides for hello world, as well as what the code provided by the maker of the youtube tutorial. They seem exactly the same, but I figured I'd try it. However, the issue is the same. WHITE SQUARES. This is for a school project and I think my partner in the assignment is getting impatient
Did you try adjusting the contrast potentiometer?
