Dont work
thank you !
Good tutorial and easy to follow.
I had trouble initially with putting .ino in wrong folder
I forgot most of what I learnt before.
Its nice to revisit Arduino again! 🙂👍

Under that code add ";" in front of Liquid Crystal "lcd(1, 2, 4, 5, 6, 7); line."
; LiquidCrystal
👍😃
Thanks Dejan for this tutorial! It is one of the best LCD tutorials out there, really well structured and produced with a high quality!
Unlike the other endless videos, you summed it up in a concise manner. Thank you!
very informative
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.
Thank you!
You made it so simple and easy to do that even I can understand ! Thanks!
Again a brilliantly explained tutorial. Clear step by step explanation. Thank you!
wow thanks a lot. This tutorial is better than my Arudino textbook haha
Agreed lol... I tried the LCD project in the book and was unsuccessful... I'm shocked that some of the projects are a bit confusing as far as what instructions are provided...
helped me a lot. I understood it clearly. could use it to read my joystick X , Y value.
Thank you for your tutorial.we were working LCD with arduino for a week searching RUclips none of them worked.once again thanks a lottt.. Feeling happy....😍😍😍😍
thanks for getting to the point and showing the cool schematic of the circuits and boards, great video!
Thank you! mine didn't work for the first time, but then I checked the wiring and it worked.
Thank's, you explained it Crystal Clear
Kosova Republik lol CRYSTAL clear badumpisshhh
Kosova Republik
lol
Looks like someone is feeling 'punny'
fuck you
Oh I see what u did there......
yayyyyy ...... I made it to nano, worked on 4 days - play video again & again ... thank you so muchhhh
Thx so much, Now I understood how to make a character in LCD screen and use this electronic
! device at all
Explanation is really great ,the detailing in coding and all s really helpful
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
Again nice tutorial Dejan Nedelkovski! keep up the good work
An EXCELLENT TUTORIAL!!! Much better than the LCD Project in the official book!!
Браво! Ясно,точно и най-важното-много достъпно!
Thanks man ! got my concept clear about lcd prog..
You may have just saved my chances of getting a degree! Thank you so much for the perfect explanation!!
same
You put so much effort into your videos! You should have more subscribers.
Ok thank you Andrew Brooks that is actually very helpful!
Thanks for such a short helpful video!
You do great work. Great tutorial, beautiful website.
HELLO RUSSIAN HAXOR! IT IS PROVEN THAT YOU ARE RUSSIAN. "Nedelkovski" is probably a Soviet Russia name. Please launch an attack on Japan!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Thanks from Australia. Very simple. you helped me teach my 8 year boy. Thanks alot
Great video.... LCD worked PERFECTLY!!!THANKS
Love it man, thanks a lot and God bless you!!!
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!
Hi Dejan, (In the right video this time)Great videos on Arduino.
I am just learning Arduinos and find these tutorials a great help.
Question, could you do one on using the "I2C" connections, I have a 20x4 LCD with the small I2C interface board but I cannot get the display to show anything.
Saciba.
Kevin.
What should I do if I want to make the custom character just stay in one part of the screen?
thank you sir, you made my day!
Awesome! I had no idea how to do it but I know now how to do it!
Thanks! It really helped me for my project at the university :)))
EXCELLENT...exactly what i needed.....great tutorial, thanks .
very very intresting tutorials , Awesome. I am learning.
Yayyyy I got it to work! - thank you!
You help to make this much easier, thanks for this tutorial.
Thanks your video is very helpful
is it possible to make a video for FM radio receiver with TEA5767 Module?
dear i am going to make a injection molding machine and want to use ardunio as programming source but problem is that is it possible to controlle time and temperature
also that is it possible to change time in controller without chaning programme
excellent, but what are the pins behind the lcd? apart from vcc, gnd. The scl and sda pins? are those optional?
Thanks for this tutorial. I'm learning a lot of knowledges from you!!!
Goodmorning! :)
I have a question.. In my project I put a 1K Ohm resistor between V0 and Ground to obtain a constant Constrast on the screen, same between A and 5V (via 220 Ohm resistor).
How could I 'justify' to a teacher my choice? Do you have any suggestion?
What could be the calculus behind my choices?
Thanks a lot in advice!! :)
I have the same problem, how did you explain it?
Thanks for breaking it down! I wanted to give a quick comment on something I got stuck on but figured out. I kept getting an error when verifying... "expected ',' or ';' before 'LiquidCrystal'", so I put a semicolon after the closing curly bracket for the array of bytes. Not sure why but that's what worked for me.
Thanks. I had the same problem and I googled it and looked for everything but didnt find anything. I saw your comment, tried it and it worked. I dont know why but it would be nice of someone knew why it worked =)
Can you show where the semi colon will be placed? Please
just go to file>examples>liquid crystal>hello world and you will see no errors in compiling and running the code into your arduino board.
hope this information helps you. :D
in c++ and c you must put semicolons after variables... lol (same for c# too i think)
yup..and this indicates that the declaration is completed
Thank you Dejan for the helpful video
Thanks for sharing this tutorial.
Thank you so much! This works and i definetly recommend this if you want to do LCD
I just got an Arduino with the lcd screen wanted to know how to use it and u explained it sooo good ..thx 'liked'
Thanks!
wow thanks. this was the best tutorial. thanks now i can do stuff with lcd
Great ability of teaching , really enjoyed
Great. Short tutorial. If you ever want to update it, you might want to show how the potentiometer and how it works.
hi my display is working fine at first, my supply is a connected to a resistor to change it to 5V(i have also used 7805 voltage regulator IC and 5V zener diodes), but then when the supply (12V battery) is being charged by a DC generator we noticed that the regulating voltages we use is not working anymore which in turn makes the LCD display random characters. Please help! Thanks
Very concise. Thanks!!!
Hello ,
I want to make waka up light thats why ı want to read time in lcd , how can ı connect rtc module and lcd?
if the display works with 4 data lines why do we need 8 of them?
Brilliant tutorial! Don't know what I'll do with it yet, but time will tell XD.
Have fun!
excellent video u solved my problem love u sir😍❤
Thank you! Wasnt able to see, but was the potentiometer able to turn up / down the brightness of the LCD display?
My display is not working, it remains off, and whenever i insert the pin from power 5v to breadboard, my Arduino becomes fade (yellow led stops and green becomes very weak). After 2 seconds of uploading command it shows error :
avrdude: ser_drain() : read error : The device does not recognise the command.
Thank you s much for this project , it has worked really well for me .
hey i need help i wrote the code as you did but it said "delay(3000) ;" was wrong.
hi, we would like to ask for help. we connected our arduino uno to 2x16 lcd, but there is a problem..it will not turn on
Thanks for complete and clear explanation
Very good tutorial, thanks!!
How are you supposed to get 2+ wires to go into the same hole on the bread board as they are shown on the schematic?
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
Excellent video! Great thanks!
Excellent. Well explained
Great Tutorial! Thank you so much!
Thanks for tutorial.
How do you draw the circuit diagram? I mean what software do you use to design the circuit?
First of all cogratulations, it is one of the best tutorials out there.
I have a question, can I use an arduino uno or an arduino mini instead?
I'm using an Uno for this and it works perfectly.
yes surely you can use other versions of arduino development board, they all have same IDE to program
make sure to select the right communication board while changing the board and for that
1. go to>start>control panel>device manager>coms port and LPT
2. now go to>arduino IDE>tools>and select the same port as that appeared in your control panel.
in order to select the correct board
1. go to>arduino IDE>tools>select board
hope this information helps you :D
Omg i was looking for this comment since I need to use Arduino Uno. Thankfully there are these guys replying to you. I'm still in highschool and doesn't know how to do these kind of stuff. Thank you so much.
No matte what I do I can not get this lcd 1602a to work i tried to reflow the board on it what am I doing wrong or is it a bad board
This is a good video. Should one resistor (usually 220 ohm) be placed in series in one of the two terminals ? Tinkercad simulation shows LCD blow with 23 mA current. I haven't yet tried on actual board.
I have the same question too.
Could you make a video on how to use the 4 terminal LCD Screen? That would help a lot!
Nice tutorial, it works!!! ty
Great job. Thanks the video.
You made my day
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.
Nice video...Really good job
where did you learn all this things bro . you are doing good job
Were is the details of each library located. Seems I can not find the page that describes what function and parameters do with in a library
Trying to do this with a 1k resistor, but the LCD keeps on blinking like its turning on and off. Any suggestions ?
This was the perfect thorough
Do you *need* all the pins? like if I don't want to change the contrast can I leave out pin Vo?
Thanks a lot ❤️ really helped me a lot ❤️
very nice tutorial ,thanks
Very fine presentation. Thanks Dejan. Every time you need to display text you need to reprogram the Sketch. Is there an LCD that has buttons to write your messages?. Second question is if you attaching an MP3; can the LCD display the played file info(the track)?. Thanks again....Regards.
After little search I found it,called LCD Keyboard Shield. Just in case people have the need to know. Thank you all.
So useful. Thank you
Hatsup to u sir very very simply understandable
Sir,
My LCD is showing just the bars that also on the top row only pls help me. And my LCD is not soldered and i m using it by connecting some wires and 40 pin. PLS HELP
Is it possible to do this without a potentiometer
Great video, this helped me a lot. Thank you!
Thanks!
@@HowToMechatronics after sometime instead of written text some other text like "0o
this man is the man thank you man
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
Could you have been using a pot with too low a resistance value? If so, you could probably also fix it with a change of pot, or adding an inline resistor.
what is the role of the 7 in createChar(7,slash) ?
Please help me i have done exactly you explain here but i got nothing. Its some time show all below blocks sometime nothing.
A huge Thanks from KR!
Hi, i want to show on/off status of 4 devices. How can i do it?
