In this chapter, we will implement our first control logic and create a simple visualization. Let's imagine a scenario where a factory has decided to automate the quality control process of their product, and for this purpose, a new hall has been constructed where this quality control will take place. However, before anything can be automated, the first thing that needs to be done in the newly built hall is to turn on the lighting so that the hall can be expanded with various automation components without any issues.
