Arduino LCD Tutorial ST7920

Welcome to another Arduino video tutorial! In this video, we are going to take a first look at this big LCD display and we are going to build a temperature and humidity monitor with it. Let's start!
I always wanted to find out a display similar to the display my 3D printer uses because it is big and inexpensive so it can be very useful for many projects. After looking around, I discovered that display my printer uses is this one. A big 3.2" display with the ST7920 driver and a resolution of 128x64 pixels. Cool! As you can see it is much bigger than most of the displays we were using so far in our projects, so it will be useful in many future projects.

So cool! Ever wanted a video with that big LCD! THANK YOU

[@iandawkins2182]

I am new to Arduino and a new subscriber to the channel. I wish I found your channel earlier, so clear and concise, even as a learner I can understand and create. Your enthusiasm is inspiring thank you so much and look forward to what is to come.

[@majorleaguegrowing]

when you said "thats why it's used in so many 3d printers" I looked at my crealiy CR10s and I was like "OWHMYGOD I HAVE ONE" its nice to have a physical reference! I was looking to use the same display because it is the right size and everything, the only thing I wish I could do is use one with a knob like the printer too.

[@tinkmarshino]

Dang.. I liked it so much that I had to get one of these displays.. down load the library and edit it all while I watched the video... When the display gets here I will make a nice little self-contained walnut cabinet for it and display it on my entertainment stand.. What a great little idea... Thanks for the share! Carry on and be safe..

[@ioannasagkioti4611]

Another interesting project. Thanks for sharing!

[@nrdesign1991]

Just as I wrecked two of these by trying to swap their LCD glasses (one of them is not an ST7920-based but looks better) you upload this video - lol!

[@DogRox]

That LCD looks bigger than the Uno itself! :-) I could see a lot of purposes for that display. Nice job! :-)

[@abhijitborah]

Thanks for showing us this new useful display.

[@avejst]

Great project, and simple application 👍😀 Thanks for sharing 👍😀

[@Educ8s]

Thanks for your kind words!

[@Rickr522]

Thanks for the video. It's big useful screen or a small price. Good to hear from you!

[@electronic7979]

Super 👍 very good

[@NewAgeDIY]

Great low cost project! I will probably order the display soon. When I get it I will design a wall mount case and print it out. Question on power consumption. Do you know how much power will it draw. Depending on that answer I will power it internally or off a wall power adapter. Thanks for making this project

[@TschenseSense]

best tutorial ever

[@gapyearkisu.6661]

omg super clear and on point, thank ya so much

[@gammacount1328]

Comprehensive, clear, usefull & emphatic tutorial Thank you Nick

[@timrisetdaninovasipelajars7389]

thank you so much sir, very good video

[@alanmitchell6132]

Thank you very much, it's ideal to replace a broken analogue vehicle clock.

[@TheDefpom]

Nice project, I always liked the idea of using I big display like that, now to think up a project that uses it :)

[@gadzw]

complete live saviour!

[@GabriadzeFishing]

Hi, thanks for the tutorial. Great Job! Can you comment please, how much current does this LCD consume? Can I use it for 4X AA battery-fed project applications? how long it will run?

[@victorhurtarte7563]

Excelent advice. Concise and professional. How can a I mode it to include a BMP180 sensor?

[@albertocabusjunior7164]

Thank you! helped a lot!

[@ElectroMentor]

Great work 👍

[@puits-de-science]

Thank you for this excellent video.

[@ARiLDSONV]

Great video! just wondering if you had to solder the pins onto the display?

[@angellocumbal1488]

you are my hero, thank you very much

[@Sixthflyer]

Great video, thank you!

[@professordragon]

My LCD is not showing anything, the only thing that works is the backlight... Please help!!

[@mhamedhamadaembaby2502]

Do you solve this problem?

[@Blink117]

Great project. any chance of making a component tester using the ST7920 thanks

[@fatonisodiq9341]

Well for me this project is useful for replacing broken analog speedometer of my old motorbike into digital speedometer

[@Educ8s]

Cool!

[@fatonisodiq9341]

@June@97 well, I actually working on it, and still struggling with it 😅

[@fatonisodiq9341]

@June@97 that's exactly the system is

[@getyerspn]

hmm I think I'm going to get one of these for my diy solar swimming pool controller..I've been using the smaller 5110 LCD display

[@samivatansever8352]

thank you sir. it's so good. god save you..

[@Educ8s]

Glad it helped

[@rostislavhruska8601]

Great. Very nice. What about power consumption? Is it a lot?

[@Avidiy]

I ordered it and it's hear super excited. Now the display I ordered has no headers and I have no headers so I ordered it but I can wait I will solder some jumper wires to it

[@Avidiy]

Can = can't sorry

[@BIOARCADE.]

Hello. I am wanting to use the full graphics reprap module in Arduino uno to use the encoder, buzer and card reader in addition to the screen. Could you do a tutorial?

[@decem_unosquattro9538]

Hmmm nice 12864 LCD ! 🤔😃👍

[@redcurtain6851]

great job

[@TheSolderingGuy007]

Great project but the title seems to suggest you will be describing the steps for driving the LCD whereas you are using an Arduino library for it.

[@intellectual_science1]

This is awesome, how can I invert the display please

[@amrkhaledelfar6724]

great thank you but i have problem how change size of font to small please ????

[@webdev723]

thanks

[@gravecop]

Thank you!

[@jontech9978]

Awesome 👍

[@deosdanygrillo3900]

exelente video donde puedo descargar el archibo IDX para proteos del st7920

[@mink99a]

Maybe you could show the project using the icsp port instead of using the mapped ports....

[@nhatthang64]

can you make another video about connecting to ESP8266 please?

[@danielgago-sk]

LCD is big, good, but working only with U8G Library and not with Adafruit what is for me better...

[@melvin.r.t8571]

ur a beast

[@shakilshaikh8047]

Hello, can you connect BLA backlite anode to 5v instead of 3.3v ? thanks in advance.

[@VeritasEtAequitas]

Read the datasheet. No.

[@rafaelmarroquin4429]

excelente tutorial, me funciono perfecto.

[@jyvben1520]

do you really need to redraw the frames everytime ? can the display be used in portrait mode ?

[@georgederleres8489]

Thanks for this video. By the way, are you greek ? Your accent seems familiar :D :D

[@Prince-cr4bx]

I want a bigger font on the lcd. How can I do that or how can I know different types of fonts in the library?

[@lahiruprageeth8555]

When using that display i cant work with another spi device ,how i fix it 😢

[@legosgameswalkthroughs4597]

thank gosh you havent quit youtube

[@TheBowersj]

can you show us how to build your own calculator using this display? Thanks

[@ever.l1549]

gracias 👌👌

How to get it connected with I2C module for 2 terminal serial communication

[@nicktranchida3990]

Did your screen come with pins or did you install them yourself

[@mehdisajjadi1679]

what about other arduinos like leonardo and micro ? i have about an I2c for this glcd but i can not find the library do you know anything?

[@addiction-69]

If 12hrs format rtc clock include with it then would be the too awesome...........

[@HelmutHassfurther]

I need the link to the DHT.h used in the sketch, have 3 different; at with therefore it comes to compiler errors

[@abdouYT123]

good

Where can I find even bigger ones?

[@elabinnovations]

Please compare these three libraries Adafruit SSD1306, U8g2lib and U8g2_for_Adafruit_GFX

[@cbm80amiga]

I have my own ST7920 library too which supports even hardware double-buffering and dithering :)

[@elabinnovations]

@@cbm80amiga That great but where get

[@MrBanatzeanu]

Hi, please help, I tried this project with Arduino Mega 2560, I configured wires to same pins as described, but nothing on screen, what I'm doing wrong ?

[@augustvonmackensen9785]

Do not connect RST - D8. That worked for me on Uno and Micro

[@plazmax]

maybe with ds3231 better to use big lcd :)

[@fateoftheuniverse3481]

illumination not working :(

[@hectorfeole869]

Dear Friend. Is it possible to use I2C with this display?

[@Educ8s]

Yes, but you have to buy an adapter

[@sarojmikubehera5039]

Can you make an egg incubator useing this display

[@owenkegg5608]

It's not like it throws off that much heat /j. I am curious what controls an incubator has besides light intensity?

[@kosa2004]

Hhmmm..... I think i will pair this display with the esp8266 chip :)

[@nrdesign1991]

It is super easy with SPI, but U8G2 only seems to work with Software SPI without modding the library slightly. See github.com/olikraus/u8g2/issues/322

[@HsiangLee-on6uc]

this LCD only expenses ¥20(about $3) in china.
