Dont work

[@decem_unosquattro9538]

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! 🙂👍

[@decem_unosquattro9538]

@@mlequuu4723 👇 byte slash[8] = { B000001 ... Under that code add ";" in front of Liquid Crystal "lcd(1, 2, 4, 5, 6, 7); line." ; LiquidCrystal 👍😃

[@MikesPikes]

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

[@husam4327]

very informative

[@samiranjoseph9793]

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.

[@malte-j]

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

[@garykahne1266]

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

[@HowToMechatronics]

Thank you!

[@daesoolee1083]

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

[@jayoli7073]

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...

[@laszlomattern]

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

[@kosovarepublik5358]

Thank's, you explained it Crystal Clear

[@sulaimaanchamda4501]

Kosova Republik lol CRYSTAL clear badumpisshhh

Looks like someone is feeling 'punny'

[@KAXSH]

fuck you

[@justicem5919]

Oh I see what u did there......

[@jochengerardi]

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

[@sparkyp0077]

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

[@antsmartti]

same

[@mohamedtawfeeq8494]

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

[@javasyndicate713]

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

[@am8084]

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

[@joachimkessler3339]

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!

[@blkr4363]

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.

[@am-1387]

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

[@Obamjur]

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

[@zammykoo]

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.

[@ottosboyen]

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 =)

[@franceababa5915]

Can you show where the semi colon will be placed? Please

[@AvikSeth]

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

[@sesame8394]

in c++ and c you must put semicolons after variables... lol (same for c# too i think)

[@AvikSeth]

yup..and this indicates that the declaration is completed

[@northshorepx]

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

[@fermitsens6234]

I just got an Arduino with the lcd screen wanted to know how to use it and u explained it sooo good ..thx 'liked'

[@HowToMechatronics]

Thanks!

[@jayoli7073]

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

[@sanjansen8143]

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

[@daxhopkins7312]

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.

[@khushidhingra6524]

You made my day

[@michaelmcnaughton1535]

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!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[@Strixzy]

Thank you so much! This works and i definetly recommend this if you want to do LCD

[@photosynthesis_by_pete4006]

Thanks from Australia. Very simple. you helped me teach my 8 year boy. Thanks alot

[@cainanlove8432]

You help to make this much easier, thanks for this tutorial.

[@tusharbanswal2089]

Thanks man ! got my concept clear about lcd prog..

[@PeterFloyd678]

Great. Short tutorial. If you ever want to update it, you might want to show how the potentiometer and how it works.

[@oraviv863]

Thx so much, Now I understood how to make a character in LCD screen and use this electronic ! device at all

[@andjroo4867]

You put so much effort into your videos! You should have more subscribers.

[@Warlordfff]

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?

[@LBSiUK]

I'm using an Uno for this and it works perfectly.

[@AvikSeth]

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

[@lanzdejillo3520]

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.

[@aonoymousandy7467]

thanks for getting to the point and showing the cool schematic of the circuits and boards, great video!

Thanks! It really helped me for my project at the university :)))

[@Laqota]

it is very important to use a resistor for the LED backlight so it doesn't burn out.

[@shahidbangash9831]

Great ability of teaching , really enjoyed

[@DinkinDallin]

Can you please explain the reason why you used a potentiometer in the hardware setup?

[@vigneshkamath4888]

Explanation is really great ,the detailing in coding and all s really helpful

[@murrrr8288]

Excellent video! Great thanks!

[@Otto_Heiskanen]

wow thanks. this was the best tutorial. thanks now i can do stuff with lcd

[@Subagyo-Tepil]

Thanks for complete and clear explanation

[@brockobama257]

Your pace is perfect. Most KZbinrs either: A) type slow and speak fast B) type fast and speak fast C) type fast and speak slow I speed up on slow typers and I can’t understand fast speakers. So both A and B are annoying. C is doable but rare and too relaxing. But you’re D) type slow and speak slow D let’s me go at my own pace. I can speed it up or slow it down on your D.

[@tejasmarulkar4432]

Ok thank you Andrew Brooks that is actually very helpful!

[@arrshithrg5359]

where did you learn all this things bro . you are doing good job

[@rafatyusufi6711]

very very intresting tutorials , Awesome. I am learning.

[@tejasmarulkar4432]

I have 4 pins coming out. GND, VCC, SDA, and SCL. Could you do something to help me out? I really hope so. You are pretty much the only arduino you-tuber that has helpful videos. PLZ help and thanks for everything. :)

[@SkullHunt369]

Awesome! I had no idea how to do it but I know now how to do it!

[@DiAngeloTheSecond]

very nice explanation

[@bolibardo1514]

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.

[@kwcnasa]

I have the same question too.

[@raygilbers8274]

Again nice tutorial Dejan Nedelkovski! keep up the good work

[@andreschavez8811]

Thank you! Wasnt able to see, but was the potentiometer able to turn up / down the brightness of the LCD display?

[@indobotacademy]

thank's for reference, i like this . now I know how to control an LCD. and don't forget to stop by our channel

Hatsup to u sir very very simply understandable

[@rahmataulia5989]

thank you sir, you made my day!

[@karimismail3734]

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.

[@karimismail3734]

After little search I found it,called LCD Keyboard Shield. Just in case people have the need to know. Thank you all.

[@indikaudayasaranga988]

So useful. Thank you

[@sparcnz]

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.

[@stefvecko6661]

Can you please make video about how to make police lights with button switch

[@RixtronixLAB]

Vote up, nice clip, thanks for sharing :)

[@tejasmarulkar4432]

Could you make a video on how to use the 4 terminal LCD Screen? That would help a lot!

[@kristofsw]

you are incredible! tysm!

[@rahmatrad4599]

Thanks your video is very helpful is it possible to make a video for FM radio receiver with TEA5767 Module?

[@rakhibamboli7032]

best lcd tutorial

[@Drxxx]

sure

[@gzcwnk]

My only suggestion on this great video is use the Mega's other numerous pins as everyone uses the same pins which is just annoying for a beginner!

[@isidorovazquez6968]

Love it man, thanks a lot and God bless you!!!

[@rishabjadhav7915]

it works great! the only problem is that the lcd screen is very dim, almost unseeable. adjusting contrast doesn't work either. please help!

[@HowToMechatronics]

Well its either LCD fault or your brightness voltage divider is not set up properly.
