Do you want to write Arduino code that you can easily read, modify, and share with other Arduino developers? Or do you already know OOP (Object-Oriented Programming) and you want to know how to apply it to Arduino? Then this course is for you. In this course, you will learn how to create a first class (for an LED component), then organize the class, and separate the interface from the implementation. Next, it will be your turn to write OOP code for a push button. Later, you will learn how to create a class to make an LED blink (how to use a class inside another class). Finally, you will get a chance to create the final TrafficLight class with high-level logic, while using all the previous classes you have created in this course. By the end of this course, you will be able to write clean Arduino code with OOP for any hardware component or functionality, rewrite your own projects using OOP, and create a clean and super easy-to-use OOP Arduino library.
