How to Interface LCD Screen With Arduino Uno

In This Arduino I will tell you how to interface lcd screen with Arduino Uno. If you are new in electronics than this article special for you. You can learn what is Arduino Uno and what is LCD screen by this article.

Step 1: What Is LCD Screen

You can see a lcd screen in Above image. In This screen have 2 number of rows and 16 number of columns. So that we can call this screen 12×2 lcd screen. This screen special Design to work with arduino uno. In this lcd screen the driver chip all build in so we not need to buy any driver ic for this lcd screen.

Step 2: How to Connect LCD Screen With Arduino Uno

Let's take lcd screen and connect all connections with arduino uno according above circuit diagram. You can use 10k or 22k potentiometer for brightness adjustment. This screen have many pins but we no need to connect all pins with Arduino Uno. Just connect 4 data pins with Arduino Uno. The screen will work great.

Step 3: Arduino Code for Lcd Screen

First you need to install arduino library for lcd screen. You can install this library by searching Liquidcrystal in library section of arduino ide. Download the test code for lcd screen by below GitHub link:-
