Character LCDs / NHD-0216BZ-FL-YBW: values for a trimpot for LED backlight?
« on: September 09, 2015, 01:04:55 PM »

I installed the NHD-0216BZ-FL-YBW display into a synthesizer, and now I have an overheating problem (the LED backlight is also too bright). The input voltage that goes into the backlight power contact is 5V.

As I understand, I have to install a trimpot resistor to Pin 15 to decrease a voltage for LED backlight.

Could you please let me know the necessary values for a potentiometer, so I could smoothly tune up the LED backlight intensity from dimmed to maximum?

Thank you,
