Hello all, I am working on the temperature sensor project, and for some reason this morning the LCD showed black squares when viewing from a direct angle, and when you look at it from the side, you can vaguely read the text. I tried swapping out contrast resistors with the same ohms rating, and that did not work. Earlier, I accidentally put in the voltage regulator backwards after taking it to re-connect the power wires. Could this be burnt out? Just now, I took out the voltage regulator for about 5 seconds, and there was absolutely no change on the LCD screen. Thanks!

Disregard. Had a minor error in wiring.
