I am building a project that requires an lcd screen. I've followed several tutorials and multiple threads on this forum but no one else seems to have the same problem I am having. I've used the following tutorials' diagrams to hook up the lcd to the arduino
I've also made sure to change "LiquidCrystal lcd(12, 11, 5, 4, 3, 2);" to "LiquidCrystal lcd(12, 11, 10, 9, 8, 7);" because those are the pins I'm using and have tried those same pins backwards and forwards in addition to trying using all the digital pins (which compiled just fine) backwards and forwards but still nothing other than a row of blocks. The pot for contrast works just fine and the backlight is working fine also.
Also some sites are saying it mattters which pin goes to what, others are saying it doesn't matter which pins you use so long as you set up the code correctly and others are saying it depends on what library. I dunno what to believe at this point.
I'm pulling out hair, it's driving me insane. I know why mad scientists in movies are usually partly bald now.
