You know that most of lcd modules need only 1mA to work (like CrystalClearTec) and some use only 100nA or even below?...juat powering off the backlight does not work, because the contents and the characters in LCd are still visible.
Ofcource my concept is to save power. but juat powering off the backlight does not work, because the contents and the characters in LCd are still visible.
The pot is external. You do not open anything. You may not have one (potensiometer/trimmer) but it is recommended in lcd documentation so you can change the contrast value.@kripacharya.....its not possible to recommend someone to open the gadget and simply turn the pot to 0...
the lcd is working on 4.2 to 5v...
but after using bc547....the lcd is getting only 2 2 v....
what should i do....
