Arduino and OOP Online Course

Arduino and OOP Online Course

This ESP32 course takes you from the basics to advanced applications, starting with setup, hardware, and software essentials using VS Code and Arduino IDE. You’ll build a strong foundation in object-oriented programming, learning about classes, encapsulation, inheritance, and real-world implementation. Through hands-on projects like LED control, IR sensor applications, and interactive games, you’ll strengthen your skills and problem-solving abilities. By the end, you’ll be ready to publish your own Arduino libraries and contribute to the IoT community with confidence.

Who should take this course?

This course is ideal for electronics enthusiasts, hobbyists, and developers who want to enhance their Arduino projects using Object-Oriented Programming principles for cleaner, scalable, and reusable code.
