I can’t seem to get the LCD to print out text

I have tried different circuit connections but can’t seem to get the LCD to print any text. Could the problem be my resistors? Circuit diagram calls for a 220 ohm resistor



Please post the code, using code tags (<code> editor button) and the schematic wiring diagram.

Also, use a multimeter to check wiring for continuity and solder joints for bridges (see below between E and D0) and poor connections.

Please read the pinned post re 'How to get the most from the forum.' Besides showing all code in code tags that has been Auto Formatted with the Tools menu, be sure to include a picture that we all can see clearly of a hand drawn wiring diagram. This is what you have actually connected, not the intended.
Google resistor codes to answer the last part.
