so you use solder for the traces? thats pretty cool.

No, to cover up the copper traces to prevent rusting/oxidiation.
I do wonder, is it possible to control the contrast with the microcontroller?
no the traces are copper as you can see in the pre-assembled pics. I put solder on the traces to keep the copper from oxidizing :D I'll have a nice in-depth tutorial in my Integrating Electronics series in part 4 :D
we posted at the same time lol. I do suppose it would be possible. All the pot does is send between 0-5V to the contrast pin, PWM may achieve the same result, but I'm not sure if the LCD will enjoy PWM on it's contrast pin. I'll have to play with it and find out. I've always just set the contrast and put a dab of hot glue on the pot to keep it where I want it.
Touche.
+rep for being on the same wavelength 500 miles away lol.
Now you've got me wanting to play around with pwm on the contrast pin lol. I'll do it and let you know :D
Thanks for the knowledge. :D
A lot of people actually use an airbrush or something similar :D
