Raspberry Pi 2
16x2 LCD display

The letter boxes around the letters stand out, how do I get them to match the background? I can adjust the background with a potentiometer, but the letter boxes still show up.






Thanks

You need to lower the contrast by adjusting the voltage on pin 3 of the LCD.

Thank you for the quick reply.

I removed the potentiometer and added 1,330K resistance to pin 3 on the LCD. The white lettering now stands out on its own against the blue background. Very nice display and easy on the eyes.
