OOP is a concept that helps simplifying your code and eases application development. It is especially useful in reusing your code. Object-oriented code enables reusing your code for sensors that use the communications interface. For example, all sensors that are equipped with a UART port could be grouped together using object-oriented code.
One example of OOP is the GPIO Zero library (https://www.raspberrypi.org/blog/gpio-zero-a-friendly-python-api-for-physical-computing/) used in previous chapters. In fact, everything is an object in Python.
Object-oriented code is especially helpful in collaboration with other people on a project. For example, you could implement a sensor driver using object-oriented code in Python and document its usage. This enables other developers to develop an application without paying attention to the nitty-gritty detail behind the sensor's interface. OOP provides modularity to an application that simplifies application development. We are going to review an example in this chapter that demonstrates the advantage of OOP. In this chapter, we will be making use of OOP to bring modularity to our project.
