Arduino LCD Tutorial | How To Control An LCD

Parts list (check website article for full list, affiliate links):

In this Arduino LCD Tutorial we will learn how to connect an LCD (Liquid Crystal Display) to the Arduino board. LCDs like these are very popular and broadly used in electronics projects as they are good for displaying information like sensors data from your project, and also they are very cheap.

Unlike the other endless videos, you summed it up in a concise manner. Thank you!

Thanks Dejan for this tutorial! It is one of the best LCD tutorials out there, really well structured and produced with a high quality!

This tutorial is brilliant stuff. The LCD was shining too bright, since I used a voltage divider in a 50 : 50 ratio instead of a pot. Made it right changing the ratio to with a 10K : 0.5 K divider.

Wonderful. A clear and straight forward explanation with no obfuscation. Very well done.

If your panel produces a random sign instead of clearing the panel try switching the first two pins (currently on 1 and 2) to other pins (I used 8 and )
It will work :)

Btw dont forget to also change the pins when you initialize the panel

Thank's, you explained it Crystal Clear

wow thanks a lot. This tutorial is better than my Arudino textbook haha

[mohamedtawfeeq]

Thank you for your tutorial.we were working LCD with arduino for a week searching YouTube none of them worked.once again thanks a lottt.. Feeling happy....😍😍😍😍

Got strange chars when I started combining it with a joystick for example. As soon as you need serial communication you might need to shift digital pins usage to avoid usage of pin 1. 0 and 1 pins are used for serial communication on this device and trigger strange chars on display. On the Uno start using pins 2, 3 instead and all works fine :P

You may have just saved my chances of getting a degree! Thank you so much for the perfect explanation!!

I made it to nano, worked on 4 days - play video again & again ... thank you so muchhhh

Note that using digital pin 1 on some boards, Arduino Uno to name one, may interfere with the Serial Port. Better use digital pin 3.

My arduino was shutting of every time i connected the potentiometer to gnd but when I connected the potentiometer to 3.5v instead of 5v it worked! Thank you so much

helped me a lot. I understood it clearly. could use it to read my joystick X, Y value.

[northshorepx]

Again a brilliantly explained tutorial. Clear step by step explanation. Thank you!

[am-]

Thank you! mine didn't work for the first time, but then I checked the wiring and it worked.

[joachimkessler]

Your LCD program worked well Thank you, I searched for a long time. I used to program with Basic, this is Pseudo Basic. Some commands and functions are known to me and hidden. Thanks again!

[Obamjur]

You made it so simple and easy to do that even I can understand ! Thanks!

[jayoli]

An EXCELLENT TUTORIAL!!! Much better than the LCD Project in the official book!!
