How to Set Up and Program an LCD on the Arduino

hello and welcome back to creative stuff..

In this video we are going to connect and test an 16x2 LCD display with ARDUINO UNO..

For the LCD display to work with arduino we are going to need the lcd we will need the liquidcrystal library of the arduino ide...we dont need to download the library ,you can find it in examples of your arduino IDE.You can use LCD display of any configuration to work with arduino using this library.

To make the LCD display work with arduino we are going to need(I have used) the following components:-
1 Breadboard
2 Arduino UNO
3 16X2 LCD display
4 10K potentiometer
5 connecting wires
6 powersupply for arduino and LCD display

Here is the full pin connections of the 16x2 LCD display:-
pin 1----------GND---------Arduino GND
pin 2----------VCC---------Arduino 5V
pin 3----------VEE---------Middle pin of 10K pot
pin 4------reg. select-----Arduino pin 12
pin 5------readd/write-----Arduino GND
pin 6------data enable-----Arduino pin 11
pin 7--------data 1--------not used
pin 8--------data 2--------not used
pin 9--------data 3--------not used
pin 10-------data 4--------not used
pin 11-------data 5--------Arduino pin 4
pin 12-------data 6--------Arduino pin 4
pin 13-------data 7--------Arduino pin 3
pin 14-------data 8--------Arduino pin 2
pin 15-------BL LED+-------Arduino 5v
pin 16-------BL LED- -------Arduino GND

Here is the full circuit schematic:

Super Awesome! I hardly will comment on here. This Guru made it simple as ever. Giving the PINS numerical values of 1-16 made it Easiest for any newbie! In 6 mins All Understood! I had to share this video with my STEM students!
Great Work! Namaste!

I have to admit i was struggling with this on my senior project, thank you for this helpful tutorial. :)

Thanks so much! for years I've wanted a working LCD screen! thank you for helping me with this video! many thanks!
I've also found a way to put different text on the screen, look at the code, it will say ("Hello World") then just change the text.
like so here ---> ("Your text here") then whatever you put in the code it will say! just a quick tip. thank you! 👍 😀

I was struggling with this from a very long time, finally did it, Thank you

[marvellmontoya]

I made mine say Hello!, with your tutorial!! Thank you so much!!

[tirumalacharikummaripalli]

This is became very simple by your explanation

[maxc]

Thanks for this bro, I hope it works, you made it really clear and easy bto understand. I apprec iate it bro.

[Skull-dhco]

thank you bro bcoz of u I got 7th rank in my school project

[RamaKrishna-hlrd]

We have to include library or not.
If we have to use means which library we have to use

[alimahamud]

can you plz help bro. I followed all your instruction to connect everything but my lcd is not displaying any character on the screen

[rathikaliappan]

Clearly explained. Neat quick and simple... hats off to you...

[bidhirudiscovery]

Thank you it was of great help in learning the LCD connections

[meawmeaw]

Thanks al brother. You saved my project 🤩🤩🤩🤩🤩🤩🤩🤩🤩👍👍👍👍👍👍

[sbslightingsolutions]

very nice tutorial, real helped a lot
😄😄😄😄😄😄😄😄😄

[ssemwangalawrence]

how can i connect it together with fingerprint sensor module such that the LCD can display sensor records

[Misc_useful]

This is exactly what i wanted... NIce one bro
