Who says you can't teach a 65 year old new stuff, Thanks

At 4:50 you solved my problem that I'd been fighting with for an hour. Thanks!

[danialbinharis]

I can’t thank you enough for this video, I was troubled with bunch of wiring on another lcd connections which require many wires and hard to troubleshoot it but this is soo useful.TQ

[mewcelappleby]

Thanks man! You were really straight to the point in this tutorial! You have been such a great help :)) Thanks again! ^^

[Crazyboyzz]

Please help me, it does not display text, but an empty boxes. And when i upload the code you gave it says no matching function for call to LiquidCrystal_2C::begin()'

[discerningillusions]

the potentiometer advice was the one I was missing thanks a lot

[BenLam]

I almost thought my LCD was broken because it was displaying lol. Thanks for the tip on adjusting the potentiometer!

[salahtamimy]

I am very thankful I was trying many videos but this the best; simple' clear; and direct to the goal; Jazak All Khaira

Good day sir! Please help me, it does not display text, but an empty boxes. And when i upload the code you gave it says no matching function for call to LiquidCrystal_2C::begin()'

my problem was at contrast potentiometer, thanks a lot bro, life savior

[nepalkoshati]

ho bro thanks for amzing vedio i like and lov vry mchu u r the bhest enginery or softwar thnx for the vedio

[rafaelbendigo]

is that the exact form of putting the i2c or for as long as you solder the i2c to the 16 pins ?
please enlighten me.

[MrStinkyPinky]

I've got lost watching your hand gestures, now I'm playing rock paper scissor alone lol. great video though

There are far to many LCD I2C library's out there that are out of date and do not work :(
The one in this video does work as of 26/6/20, I spent a whole day trying to fix the LCD only displaying one character and compile errors caused by the published fix's for it :(
This worked straight out of the box, although I downloaded the zip and extracted it to C:/Program Files/Arduino/libraries instead of using the include method.
Thank you :)

Heya, it was nice explained!!
Can u tell me why we attached the ir sensor to back of lcd display?
What is that's use ?
Can we add lcd to aurdino without that sensor

[robyray]

Hi i'm not an expert so i would like to ask you if you can add some lines on the sketch to add the reading of microSievert/h as well as the CPM? The conversion index is equal to 151, which means that: 151 CPM = 1 μSv/h
1 CPM = 1/151 μSv/h = 0, 00662252 μSv/h.
Thank you

thanku very very much bro
I am searching for this content for 2 days
that part which you explained that 16, 2

I'm unable to open the example file. The library is downloaded, but whenever I go to open the HelloWorld example, nothing happens upon clicking it. Do you know any way to tackle this issue?

[ZothiamaCF]

Thank you. A great tutorial that is clear and to the point. Again thank you very much sir👍👍✌️
