Arduino and OOP Practice Exam


About Arduino and OOP Exam

The ESP32 is a powerful microcontroller used in a wide range of IoT applications due to its robust features and versatility. This course provides a deep dive into ESP32 programming, combining hardware understanding with advanced software techniques. You'll start with the basics, including the ESP32 pinout and IDE setup, and progress to mastering object-oriented programming (OOP) principles to create efficient, scalable code. Through practical projects like LED control, IR sensor applications, and interactive game development, you'll gain hands-on experience. By the end of the course, you’ll be able to publish your own Arduino libraries and contribute to the IoT community.
