Let's review another example where we implement a simple daemon using OOP that turns on/off lights at specified times of the day. In order to be able to perform tasks at scheduled times, we will make use of the schedule library (https://github.com/dbader/schedule). It could be installed as follows:

Let's assume that the light is controlled using PowerSwitch Tail II (http://www.powerswitchtail.com/Pages/default.aspx). It is interfaced as follows:
