I have checked my connections again and again, and I cant find a problem.
... the only confusion is the LCD nas "negative voltage output" pin, and I read that some LCD's need negative voltage. Could this be it, and if so how do I accomplish that?
I have the variable pin (I assume for contrast) connect to VCC via a 10K resitor
I have (pin 18) Vout going through a 10K resistor to Vo (pin 3), I then have a 10K resistor going from pin 3 to vcc.
Has anyone a small program that I can use to test if the lcd is working,
they say 10-20K
I would have thought If Im getting nothing through te issue would seem greater.
