Bill, Yes im able to adjust the pixels from all off to all on and middle setting too.
I haven't hooked the Vee to anyplace its lying like that im looking for the right pin on the pot to hook it too and now as per your sayings it has to be linked to the Gnd on the pot.
Currently im giving the following connections to the pot:
+5v(of arduino) and +5v Backlight-----(Middle)V0_Contrast-----Gnd and Gnd of backlight
and also in the datasheet its written that logic and LCD operating minimum voltage is 4.5v im giving 4v , is that a issue too?
Moreover as i click the 1(Power) and 2(Gnd) pins to the Arduino power supply the Arduino's system goes OFF(i mean power LED etc goes of) is LCD that demanding on mA's?
And, Yes im running the following GLCD example:(Compiling Fine!)
/*

* This code exercises a range of graphic functions supported
