Are you worried whether your 16x2
Lcd is working or not? Are you worried whether it is burned or working well? Here is the
solution, just follow the below steps to find your solution...
FOLLOW THESE STEPS :
>> Connect the pin vcc pin to
5v
>>Connect pin Vee and gnd pin
to ground
>> Connect Led+ to 5v
>>Connect led- pin to ground
After you made these connections
then Lcd look somewhat like this below i.e the lower line will be brighten..
If your Lcd is not working well,
then both the lines will be bright shown below
Important Note: Most Lcds can
withstand upto 9v( but not all), and dont worry if u
applied 9v without knowing it.. Do
above steps with 5v only...

I have an LCD Display removed from a clock, do you know how test it.
I guess such type of LCD are customized and terminals are unknown but there could be some way to test it.
Pls advise.

Help please..
My LCD doesn't even light up (jhd162a) after making the above connections.. Can this happen??
Thanks. My LCD backlight wouldn't light up... could only see the text vaguely. After connecting it like this the backlight lit up again. It somehow resetted the LCD back to normal.
I cant see any blocks on my lcd but it is glowing what could be my problem
Thank you, it helped me not to throw away my 1602 :-)
in your statement for testing 16x2 you state the lower line will be bright. then you make the statement that if your LCD is not working both lines will be bright. If step 1 is working how do you test the top line?

Thanks. I needed this to notice my chinese Arduino is the part which was acting up. Lost half of my nerves before searcing this and now, at least, i have the other half left to lose with some other project ;D

...and i just had to come back and tell that the failure was not in chinese Arduino, but in one old fools brain.
Note ToSELF: + and - break in middle of your breadboard. Jump them and you don't have to spend the rest of the night begging forgiveness from the innocent chinese you've insulted.
