How to Use an LCD With an Arduino

This is a step-by-step guide on to to use an lcd with an arduino. It is very simple. If you still have question leave them in the comments. Here is also a video to make it easier:

Necessery:

-Arduino,

-wires,

-LCD(2$),

-computer (to programm the arduino).

Optional:

-Breadbord (RECOMENDED!),

-potentiometer/resistor.

It is welcome to have a bacis knowlage of arduino programming, but you can also go without it.

There is not much to say about wireing follow the schematic if it confuses you watch the video here:

i cant really explain every line of cod here, so i will just breafly explain (Beginner tutorial:

We are using an example from Liquid crystal librery.

1. #include

2.configure the pins

3.lcd.begin(16,2); -(screen resolution)

4.lcd.print("Hello, World");

5.Upload - Make sure the correct board and COM port are selected!

Now writing the code like this will result in an error this is just an overview.

This part is important is helps you learn more about arduino you can make a simple game on it, on you can display data from diffrent sensors. Thanks fore reading.
