For the past two weeks I have been using the Arduino. I’m having trouble wiring up a LCD 1602 to my Arduino. I know there are other posts on this specific LCD however I can’t seem to find any similar to my issue. I have done so much research and cannot seem to find what I am doing wrong here.
I wired up 3 of these LCDs and end up having pretty much the same result. I can’t get past the Squares although I am using a Pot meter. I wired the LCD directly using jumpers and also header pins just in case it was something with my soldering but same result. Right now I am able to see the squares but when adjusting the pot I see ‘broken text’ and weird symbols on the screen, if I continue turning the POT meter the screen goes blank although I have the HelloWorld script loaded w/ the LiquidCrystal Library, I am still unable to see any clear text.
It could be anything else as I am no expert but I am assuming the broken text is either caused by either incorrect wiring or a shortage. If anyone thinks its a shortage I can switch to one of the other wired screens. I followed two different tutorials with pretty much the same result.
I updated my Helloworld script to reflect the following:
LiquidCrystal lcd(7, 8, 9, 10, 11 , 12);
Sorry for the huge pictures. Wanted to make sure they’re as detailed as possible. Thank you in advance.
