  • I believe he choose a 2k instead of a pot to adjust the contrast. I’d keep a pot, perhaps a 10K on there to adjust it if you please.
    Someone noted above that the voltage needs to be fairly low (~-4V) to see the darkness of the pixels. If you hook a pot up, be sure to wipe it to both extremes to see if you can atleast see a big black box when the LCD has power, then you know atleast your contrast works and you’re getting power!

No public wish lists :(
