LCD backlight too bright
erhanalankus commented
Use PWM on pin9 to turn on backlight. Code in brightness values for time of day. High brightness for day, low brightness for night.

Swapped pins 9 and 2. Implemented previous comment. Should the backlight be always on at daytime?

Now backlight is always on. Brightness is determined based on time. A button on ir remote turns off backlight until the alarm is active or 9am.
