  • Thanks for the info. I was quite careful about the voltages being supplied to the LCD, but I’ll check again (and verify the contrast voltage).

  • I purchased one of these and hooked it up to my Arduino Mega according to this page:
    http://www.arduino.cc/playground/Code/GLCDks0108
    I grabbed the software and loaded it. The backlight works and at first I saw a few lines on the display itself (these faded). When I ran the software from that web page, nothing came out on the display. I played with the contrast potentiometer a little, but I still see nothing. The program is running (I added some Serial output for debugging).
    Is it possible that I burned out the controller? Or… is it possible I just got a bad one? Does anyone have experience with these that might be helpful?
    Thanks!
