Im so very thankful for your video, i spent 4hrs just to make my LCD i2c to run but end up in to nothing so i search here in yt and your vid is very big help for me thanks to you hope your channel gets bigger🤙🖤
@@TeachMeSomething bro one more thing...It's working properly but contrast seems to be dull...The text is barely visible....Can you please help with it 🙏🙏
Best method for such problem will be to tighten or loosen the screw behind the i2c module in a small blue box(potentiometer of display) it will change the contrast of display due to high or low contrast these boxes appear. This solved my problem hope will solve yours also
omg thank you so much for this! i was doing everything as this guy was saying & what i read from the library documentation and could not figure out what i was doing wrong.
I have a 20x4 lcd with i2c module, but lcd not show any word only show 80 box. I set potentio meter , but noting show on the display. Please give me solution.
Heyy, my lcd screen works good but when are working a few minutes start to do the same like your screen in te minute 4:48. Can you help me please?? (im using a lcd 16x2 with all the wires)Thanks!!
Hi sir, my LCD is not working SCL and GROUND pin on my lcd with backpack are shorted when i check it with tester is that normal? If not how can i fix it? thanks for the reply.
@@TeachMeSomething Nah, I figured what the problem was. The scl pin on the control board was touching one of the resistors or the capacitors on the lcd board. The factory did a bad job putting it together, should have put something between the 2 boards. I am just glad the chip didn't fry.
i did try everything the metods that you mentioned, but it still not working. For example when i click the reset button from arduino the lcd turned off and i idid adjust the potentio. Does it mean i should buy the new lcd? pls fast respond cause this is for my bachelor's degree, thank sir
@@TeachMeSomething look there was a program to check your i2c address but in my case i brought 2 i2c and 3 lcd in both i2c model it is not showing i2c address its say i2c not found also i try many program of lcd but still those boxes came up on only one side so please on that do you have any Instagram id so we chat on tha
@@TeachMeSomething bhai mere pass code hai jisme 16 pins use ki hai lcd ki aur maine I2C module use kiya hai toh maine 4 pins use ki hai toh video bhejo na koi changes krne ke liye
This rocks. QAPASS 1602 is cranky and net isn't helping with this one. This solve worked first time on all my devices. Not frustrated any more.
you helped us labyu from cosganians love you from the bottom of my heart

This is the problem on the LCD 2004, the backlight and white cubes, but the Arduino does not see the I2C module. how can this issue be resolved?
Connect sda, scl properly

Sir, it is only a loose connection or soldering issue only.
Please check it.
Dont touch your lcd. Keep in the proper place.
plss help me it said on the serial monitor that No I2C Devices found
Connect sda,scl pin properly
Thank you
You're welcome

Hi sir, my LCD is not working SCL and GROUND pin on my lcd with backpack are shorted when i check it with tester is that normal? If not how can i fix it? thanks for the reply.
Check i2c address first
Sir SCL and GROUND pin are shorted when i check it with multi tester in my backpack ice cord c are those really shorted?
THANK YOU
half of the reasons are libraries not installed or a different version, or the lcd not initialized in the sketch.
I know but any way to find the version of the code it was used?
I have a similar lcd that doesn't work. Scanning the i2c bus just hangs and doesn't progress at all, so I am guessing I have one with faulty i2c chip.
May be
@@TeachMeSomething Nah, I figured what the problem was. The scl pin on the control board was touching one of the resistors or the capacitors on the lcd board. The factory did a bad job putting it together, should have put something between the 2 boards. I am just glad the chip didn't fry.

Then also led screen is not showing any thing what to do after that
Found itc address?
@@TeachMeSomething yes everything
Itc adress, liquid crystal i2c library and all
THANK YOU SO MUCH!
Very helpful. I thought my lcd isn't working, but only to adjust brightness 🔆 to see what's behind it. Thanks.
If you know, it is easy.
If you doesn't know, it is difficult.
how did you adjust your brightness?
At the back of lcd i2c, there's a potentiometer to adjust brightness with small screw driver.
@@victorianogubatan569 did do that but my lcd screen has just light
@@jojosanitytv8150 if it darkens or brightens when adjusted, lcd i2c is working. you need to upload code to see the output.
GRACIAS, me sirvió
Thank you

Give 5v or Vin for LCD vcc pin.
Try both
Did it work?
Same problem
No my lcd is not even turning off when i restart the arduino it just shows some rectangular figures (sorry for my english)
