I'm trying to connect a LCD 16x2 display, but as a matter of fact, something is not working well..
What I get when I try to display something is mostly zeros, squares or strange numbers.
I made a vid so it would be easier to understand.

I followed this tutorial and copied the exact code + cabling :

I'm really not understanding why anymore, checked all cabling .. Do you have any idea where could it come from ?

Thanks in advance !
UPDATE : I didn't really change anything but now I get two lines of strange symbols/swuares ..?
UPDATE : No, it just changes whenever it wants ..
