Hi guys !
I’m new in the comunity of Arduino. I’ve bought an Uno for a week now and it’s really rocks.
However I have a problem with my 16x2 LCD, indeed, sometimes it works very well (I can print what I want) but sometimes a pixel line doesn’t appear on the first row of the LCD (even not contrasted, just not appearing like a corner of the LCD screen…). Sometimes a reset solve the problem but sometimes not… I checked contacts and wires many many times and they are ok.
One times, I unplugged the LCD and plugged it wrong (I shifted it, so every connections were shifted too) and when I plugged it good, I see for th first time the problem. Any link ? Now, a good way to solve the problem is to shift the LCD of two pins (it doesn’t work, obviously), don’t ask me why, but when I plug it good after that, it works and the blank line disappears…
I don’t understand, is it an hardware problem with the LCD, problem with my breadboard, software problem ?
Thank you for your reply !
