I got an LCD with backlight provided by 15V LED. If users leave the LED turned ON for long time, it will shorten the life of the LCD.
I would like to be able to turn OFF the backlight LED after some 5 minutes of non-use.
But I do not have good idea how to do it.
How to use the PIC to control 15V line going to the LCD, and turn it ON/OFF?
If someone has any idea please let me know.
Thanks.
