    Hi, sorry very new at this. Got this 3.3V 16x2 LCD for my first LCD project and hooked it up. Working but any idea why the top two rows of dots are not working? I tried the “hello world” sketch and every character that’s larger than the ‘e’ or ‘o’ is cut off going up. I have it hooked to a pot and if I turn it all the way up the bottom row of 16 is correct, 16 black boxes, 5x8 dots in size but the top row is only 5x6 dots and I can just about make out the tops of the ‘h’, ‘l’s, and ’d’ in “hello world”. Checked voltages, everything looks right. Soldering looks ok for a newbie(nothing loose). Any ideas?

No public wish lists :(
