while connecting Lcd Display with Arduino Uno it is displaying some other language and question marks
we are using Hello world code from example.
Kindly Please Reply ASAP.
If you want an answer as soon as possible you should at least tell us what display are you using, what libraries, what examples you are running, how did you wire the display, post an image...
Do we look like fortune tellers hovering over a crystal ball?
Apart from a couple HelloWorld that willingly display hello world in russian, japanese, korean, chinese etc etc, in order to show they can display other alphabets, I'm sure no library will bother to display anything else, surely it won't translate anything in any different language you didn't ask
Please be reasonable. It's a board. You program it. It's not a crazy demonic baby with its head bending backwards shouting blasphemies.
Now... please give us more information and please understand that there is a difference between gibberish and a proper language.
If your lcd displays "Ciao a tutti!" instead of "Hello World!" it's the example willing to do so.
If it's displaying "edbgv47erv 75 ve.3b vdsewrg?=??" well, this is not some other language, but a problem of wiring.
