Hello, noob here. I ordered an Elegoo Most complete starter kit of amazon yesterday. Many projects went well. But for hours I"ve been trying to get my LCD screen to show something. The best i did once was that it displayed the text but it was mirrored(?). Right now all it does is change the background color when i upload the code. But anyway, I would like to know a few things like.

This is slightly difficult guide for the beginners as it involves soldering and wiring is complex. Here is detailed steps on how to for 1602A LCD display Arduino connection. In this guide we will also talk about the soldering part. The units do not cost more than 3 USD per unit but there is no in-built pins – usually male header pins supplied. We talked about different types of wires in electronics. We can use solid core wires instead of male header pins and solder. Arduino has the needed Library included :

With the above connection, again connect your Arduino with computer, the LCD will light up. Adjust the potentiometer and you’ll be able to see from blank to white all units like [] [] [] []. That [] [] [] [] is full contrast and blank is minimum contrast.
