[@salemBerihun]

I didin't know where the potentiometer was at first, you are the best thank you so much 😊😊

Thanks bro,it's very helpful

[@sakibnahid9423]

Awesome video bro.

[@mohdfahad9384]

Brother, I have done exactly as you explained but I can't figure out though the display is glowing no text is visible. I tried adjusting the potentiometer also and that address code didn't work for me.

Did you solve the problem?? Because we are getting the same problem

[@mohdfahad9384]

@@Amateurartist111 yeah I wrote the same code in loop, then it worked

[@mohdfahad9384]

@@danial579 well , just take the code from setup and copy it in loop

segun ChatGpt Vin es una entrada de voltaje que permite alimentar el microcontrolador y ahi lo ocupan como salida?...en los nodemcu que tengo aca, ninguno entrega voltaje a traves de ese pin

WARNING: library LiquidCrystal_I2C claims to run on avr architecture(s) and may be incompatible with your current board which runs on esp8266 architecture(s). what to do if i am getting this warning

[@INOVATRIX]

Just a warning not much else, the code is fine and should work as expected.

How many button added to this project

[@bruhblox_]

3v dosen't seem to be enough at all, I can barely read the text and its not even connected to any other components

[@tech_xavier]

if the length of characters is more than 16 in a row, then how to display all the characters by scrolling a line ? will it auto scroll or we should code for it ?

[@INOVATRIX]

You will need to code it so that it scrolls through the display. Many people have done this way also so the code for it can easily be found l.

[@habibrobotics]

why you didn't mention the sda and scl pins connection ina code

[@INOVATRIX]

Those pins are pre configured in the library so no need to declare them seperately.

[@hemantraghav1800]

Can we connect the data pins of the lcd to any D pin in nodemcu?

[@INOVATRIX]

No, as we use a library it uses SCL which is serial clock and SDA which is serial data pins on the board. Only 2 pins can do this task.

My work LCD i2c and Ardino ESP2866mode MCU and DHT11 sensor not taken reading code

[@nothingpersonal.5901]

Did you manage to solve it

[@christianbaldoza1666]

my lcd doesn't work huhu

[@PadmajaReddyVirupa-yt6ch]

Brother can you send the code plzz

[@K.TFITNESS]

Can u please help us out in our project beacuse we are facing lots of issue

[@K.TFITNESS]

Btw your code is working properly
