Add a LED background light control circuit to the smart controller by shorting pins to keep the LED on continuously or turn it on for 30 seconds then off automatically. If you usually start printing jobs at night, this modification ensures the LCD backlight won't bother you anymore. You can adjust the light-on time from 10 seconds to 2 minutes by trimming R4 (100K). The controller is fully compatible with the original design, so you can use the original RAMPS adapter.
