Arduino for Beginners - 2022 Complete Course - Activity 05 - Create a Small Traffic Light System

The video tutorial guides viewers through creating a simple traffic light system using three LEDs. It explains the sequence of powering on the red, green, and yellow LEDs to simulate traffic light behavior. The tutorial emphasizes that the color of the LEDs is not crucial, as any color can be used without affecting the program. The instructor encourages viewers to practice creating the system and promises a solution in the next lesson.
