Lcd Not Displaying Anything. #include <liquidcrystal.h> liquidcrystal lcd(12, 11, 5, 4, 3, 2); Check the connection between lcd display and. What are the possible causes of a lcd display not working with an arduino? You can try restarting your computer to. The slider will be about 0.4v. You should adjust the pot for contrast. If the lcd is getting power it should display a row of blocks on the top row, even with the data and control pins disconnected. The lcd is working perfectly fine (hardware side). Some lcd's need a negative contrast voltage, check the datasheet of the display. Check the display’s backlight, the liquid crystal. If the contrast voltage is not correct. If your lcd display is not showing anything, it’s possible that there is a software glitch. Only 2 changes require in your code. Yes, your 22r backlight resistor should stay there. Many times people ask questions about how to fix their lcds that don't display or displays wrong/random stuff.
