1602A LCD

I am trying to hook up an lcd and it won’t display text. I just want to run the “Hello world” program.

You have to post more detailed information if you want to help. I hope it is not just notice.
Post the wiring diagram, your sketch, which Arduino and LCD.

Welcome to this forum.

When posting your sketch pls use the code tags “</>”-Button; you will find the button on the “quick Reply” menu leftmost. As a newbie it would be helpful (for you and all supporters) if you read and follow the guidelines of this forum. You will find a link to the guidelines in my signature.

This is kind of like saying:

I am trying to bake a cake in the oven and isn't baking. I just want to eat the cake.

Without more details it is impossible to know how to help.
