Hi all !

I'm sorry if my question is very novice :disappointed_relieved: , however my problem is :
I tried to connect the character 16*2 LCD exactly like what was explained in this article

first temp I found my LCD have full light contrasted black blocks and I used trimpot (which I used as potentiometer ) then when I uploaded the code nothing appear on the screen .

second temp : the LCD didn't appear anything even black blocks and when I connect the GND arduino UNO R3 switch off as if something make a problem .

third temp : I change the configuration but even that it didn't work .

P.S: I don't think the LCD break out or some thing .

my LCD PINS are in this order : Vss Vdd Vo RS R/W E DB0-DB7 A K it's SD-DM1602A .

We cannot help you very much unless you can provide a photograph showing how you connected your LCD.

You could try following this tutorial: Arduino Tutorial - connecting a parallel LCD.
