Arduino OOP - Modify the LEDs Brightness with the Potentiometer

The video tutorial demonstrates how to integrate a potentiometer into a traffic light system to control the brightness of LEDs. It covers the inclusion of necessary headers, updating LED brightness using a new method, and implementing PWM for brightness control. The tutorial concludes with testing the system on an Arduino board, ensuring the potentiometer effectively adjusts LED brightness. The project is organized into manageable files, making it easy to add or modify functionalities.
