NexArdu: Illumination Smart Control

A sketch to control home illumination in a smart manner via 433.92MHz (aka 433MHz) wireless X10-like devices, e.g. Nexa. When it comes to decorative illumination, it has been somehow tiring to me that every second or third week I had to readjust the timers that switch the lights on because of the shifting of the solar hour with respect to the CET. At the same time, some nights we go to bed earlier than other. Because of this, sometimes the lights switch off either “too late” or “too early”. The above challenged me to think: I want the decorative illumination to switch on always at the same level of ambient light and then switch off at certain time depending on whether we are awake or not.”
