my LIGHTHACK work very good except lcd dsplay, do you have any suggest?
All connections to the display ok? Connected to the right pins? Contrast potentiometer?
i think that all conection culd be ok...contrast potentiometer do not have affect...i think the pin's connection is right..
At fist switch on.. i see two differents light intensity of lcd full lines...after upload arduino firmware lcd is darkened, with led on lcd display is in ON..
what do you think?
Did you connect it to a nomad or console? After connection try the contrast potentionmeter.
