Lesson: 22- Arduino OOP Tutorial for Beginners | Classes, Objects & Custom Library Files (.h & .cpp)
Hello and welcome to Electro Nerds Academy! In this beginner-friendly Arduino tutorial, you’ll learn Object-Oriented Programming (OOP) step-by-step. This video uses the classic Blink LED example to show how OOP works in Arduino.
What You Will Learn In This Video
✅ What is a class in Arduino?
✅ What is an object or an instance?
✅ How constructor works & writing constructors & using parameters
✅ Constructor overloading
✅ How to use public and private access specifiers
✅ Making private and public variables
✅ Writing a Start() function for blinking the LED
✅ How to write .h (header) and .cpp (source) files
✅ How to declare your class in a header file (.h)
✅ How to implement the class in a source file (.cpp)
✅ How to include custom classes in your Arduino sketch
✅ How professional Arduino libraries are structured
✅ How to convert your code into a clean Arduino library
⭐ Why OOP Matters in Arduino
As your projects grow—using sensors, displays, motors, modules—your code becomes long and messy. OOP helps you:
✔ Organize your code
✔ Reuse functions easily
✔ Create modular, professional-grade Arduino programs
✔ Build your own custom libraries
