My screen has no pins to plugin they came not soldered? Should I solder it

[@danialbinharis1953]

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

I can’t Thank You enough to for this . I was traying so many examples but NO one worked ... Thank You again 🤝

thank you!

[@steverpcb]

There are far to many LCD I2C library's out there that are out of date and do not work :( The one in this video does work as of 26/6/20, I spent a whole day trying to fix the LCD only displaying one character and compile errors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 :)

[@aymaanra]

I'm glad it worked! Cool! Any projects you are planning to implement the LCD Display into?

[@steverpcb]

@@aymaanra I am initially going to use it to display values to help debugging code, the current project is temperature controlled cooling for a large radio control aircraft to automatically open and close the vents. This will eventually be on a custom PCB using an atmega328p-pu with the option of connecting the LCD to show the sensor temperature. While not from my project this gives an example of what it will operate kzbin.info/www/bejne/o3Scq2mHgtCafNE

[@steverpcb]

Interestingly all the DIY arduino tutorials that I have seen appear to be wrong, they either do not mention the load capacitance of the 16mhz crystal or they use the wrong value load capacitors e.g. using 20pf capacitors with a 20pf crystal instead of the correct value of 36pf. Indeed many sellers of 16mhz crystals on ebay, amazon, etc. do not give the load capacitance :(

[@aymaanra]

@@steverpcb wow, very cool!!!

[@aymaanra]

@@steverpcb oh so are you planning to use atmega then or an arduino nano or something similar?

[@scienceboyakshansh5378]

Same is happend with me, try typing "lcd.begin(16, 2);" if you have lcd 16 x 2, and then upload the code, for me it disabled the backlight, then I typed the previous statement lcd.begin() and it worked.

you cant get the library anymore

[@xsimplybeny4095]

Who knows. It is possivle to leave this lcd on with text what we wrote on script without connect with pc?

i have a problem, i used 5 pins of 6 analog pins, and i need to connect lcd with i2c also. where can i put sda, scl pins on arduino?

[@wanjohimuthoni]

Only getting white printed boxes, that is, pixels displayed but not message

[@robyray5644]

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

[@milk6-]

Hi, i had adjusted the potentiometer for the lcd.. bur why still it doesn't appear any text ? I did upload the exactly code you share and no error at all

[@kritijain9619]

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

[@danilolazarevich]

It is for background contrast of display

[@marvinrebanal3595]

How can scroll the second line without moving the 1 line.like 1st line, print hello. It static. While the 2nd line is scrolling to right to left. Hope you help me

[@ireshafernando1029]

no matching function for call to 'LiquidCrystal_I2C::begin()' what is this bro

[@moreolakunri1322]

great video, thanks

[@aymaanra]

You’re welcome!!

[@TIKHONLOMTEV_SLO]

They say, lcd.begin(); is wrong why?

[@tayyabahashmi1584]

Sir what are the functions of SDA and SCL pins and why we connect them to A4 and A5?????

[@mowtown75]

I thought same, note that some Ards have dedicated pins labelled as such on the digital side north of pins 12, 13. Mine Ard Uno does.

[@nishanthhudeda7298]

the library in github is now read only... it has been archived by owner.... Where else can we get it....????

[@wanjohimuthoni]

Mine just display white square dots, what is wrong

[@harsimrankaur8055]

Whenever I interface, i2c heats up. Can I know the reason behind it???

[@rafaelbendigo6270]

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.
