How to Set Up and Program an LCD on the Arduino

How to Set Up and Program an LCD on the Arduino

In this video, I briefly show you how to connect a 16x2 LCD to an Arduino. After that, I go in-depth into which functions are available in the LiquidCrystal library to program it, and show you what they look like on the LCD. I also explain where and how to use each function in your program.

This was my first attempt at something more complicated than lighting up LED's with a potentiometer. My kids and I were thrilled to see everything working according to the description. I went through the video and made my own notes on how to connect the LCD to the Arduino, then followed my notes for the actual connection. Everything worked perfectly with my Elegoo Arduino Uno.
My next step is to tear it down and rebuild it over and over again until I can do it by instinct.

LCD to Arduino

pin1 to ground
pin2 to positive
pin3 to 10k pot midle (other pot pin to -ve and +ve)
pin4 to A12
pin5 to ground
pin6 to a11
pin16 to ground
pin15 to 220oh to positive
pin14 to a2
pin13 to a3
pin12 to a4
pin11 to a5

These have been the most useful videos and articles I have seen on the Arduino so far. Arranged just like I learned BASIC years ago. Started with clear, concise instructions on assembly, then to simple programming, and then modifying existing builds to incorporate new coding. Very helpful. Thank you very much. I learned so much in the past hour than I have in days from know-it-alls who think I should have known where serial monitor was.

its ppl like u who make this hobby so accessable to the noob (ME) ur adding so much to this community and for that i doff my hat....keep the vids coming

[brettpenza]

This is great. I was wrestling with this for 4 hours with other videos, some with annoying background music and zero instruction. This is great. No stories, political opinions, ridiculous background music. Just right to it. Excellent work, Thanks very much.

Thank you so much man. i have watched over 25 videos and this is the only one that worked. you just earned a new sub and like :)

[burhannaveed]

Guess who got a sub??? You!!! Amazing video and very easy to understand.

[amtpdb]

I appreciate the way you took us through this slow enough that we could do it along with you (with the stop button). I think I got more from this then alot of the videos I have seen that did not address WHY this was happening.
Thanks for the great video.

Excellent video! There are lot of them out there, but you explain it so nicely, easy for a newbie like me to understand. I am a programmer, but new to electronics itself.

I am Autistic, I am great with wires but poor with computers, I found this video very helpful and not over powering. :-)

9 years later and still great tutorial thanks!

BRO I JUST JOINED AND I LOVE THIS GUY. HES SO CHILL

[kristofferd]

THIS IS LITERALLY THE BEST VIDEO ON YOUTUBE. I HAVE BEEN TRYING TO FIX MY LCD FOR 2 HOURS, BUT SOMEHOW IT WORKS NOW TANK YOU :D

[tobiasgamified]

I actually detected an error in this setup, in the video he is connecting the end of the resistor to the MINUS current, it should be connected to the PLUS current, connecting it to the minus current will cause the display only to use back lightning, while putting it into the plus will make the lcd screen glow as it should :) hope it helps

[marklaurence]

Clear concise and easy to follow, great video. your expanded label descriptions are very informative

[vicktells]

love you bro, this helped me a lot. this made me look great in my parents watch of me getting good at arduino ...

[adrianwilliams]

Nice clear tutorial. Liked the way you started by demonstrating how the lcd screen was wired to the Arduino.

[blakecraft]

I FINALLY got my LCD screen to work thanks to this video. You, sir, are one helpful human.

[grahamevans]

This video saves hours of confusion, it's beautifully created and presented. Thank you for making life easier for me sir.

Thanx.. Just got my Arduino kit. First program was blink to show an LED going. But I saw that LCD in the kit and wondered if that would be too complicated for a next step. Found your vid and tried it.. Worked first time! (Well, the only POT I had was a 50k, and I didn't see anything at first and had to go up quite a bit before I saw the display, but it worked.) Thanx!
