  • Contrast control does not work. I have a 10K pot connected between +5V and ground with the arm connected to Pin 3 as per the datasheet. Varying Pin 3 from 0 to 5V has no effect - the display remains blank. The backlight is working. The only other connections are: Pins 1 & 16 to ground and Pin 15 through a 470R to +5V.

No public wish lists :(
