I bought a budget lcd screen years ago and never got it to work. Just followed your instructions and it worked first time. Well done on such clear instructions. I had already coded my Arduino to put something on the lcd so I didn't use your code example but it was quite happy to work with the display.

[@blobberv9638]

I loved how you explained everything using tinkercad, made it really clear and easy to follow

[@handletodizmantle]

thanks dude works perfectly and is my first try as a noob

[@khaleeqali-ew7sk]

100000/10 would recommend

[@khaleeqali-ew7sk]

omggg it worked i and i am only 13

[@nikajobava481]

I think it would be good to do one about rotary encoder and one about I2C 0.96 inch lcd

[@kaito-ww1yd]

wow, this channel gave me act like a horse !

I am using D1 Robot 1602A LCD shield.. I counldn't find the V0 pin :(

[@topquark22]

In the tutorial it says that the device uses SPI, and uses the MISO and MOSI pins (12, 11) but I don't think this is accurate. The device does not use SPI and you don't need to use pin 11 for Chip Select. In fact I can't do that, because I have other devices on the SPI bus! I think this part of the Arduino Tutorial page needs to be corrected, as well as the example circuit.

To clarify - you're talking about the Arduino website and not our tutorial, right? If so, you'd need to submit this comment to them directly; we aren't officially affiliated with Arduino.

The module I got has 4 wires sticking out the left-hand side of the board. What is that for?

[@Science.Buddies]

We can't say for sure, you would need to check the datasheet or instructions for the module you bought.

[@topquark22]

To answer my own question: Turns out the one I got is I2C. It is so much easier and uses fewer wires!

[@isomer805]

can you once give the me the exact link of the code.Actually i was bit confused of the above one given in the description box

[@Science.Buddies]

Hi - the code we're using in this video is identical to the code from the links in the description.

[@chese1976]

what kind of resistor is it

[@chese1976]

nvm

[@zoomyjo]

I connected everything but the arduino didn't work when i tried removing the 5v from the arduino the arduino worked but the lcd didnt cuz there isnt any power so what do i do??

[@zoomyjo]

pls anyone reply I really want it to work

[@Science.Buddies]

Hi - we can't really help troubleshoot in KZbin comments, we recommend asking on the official Arduino forums where you can also post your code and pictures of your circuit.

[@zoomyjo]

@@Science.Buddies Ok thank you for your help !!

[@m.ramadevikrishnaprasad7771]

Can we plug the LCD on to the bread board

[@Science.Buddies]

Yes, if it has header pins you can plug the LCD screen directly into the breadboard.
