In this lesson, we will explore how to program the Smart Car to follow your hand. This exciting functionality is achieved by integrating both the Ultrasonic Distance Sensor and the Infrared (IR) Obstacle Avoidance sensors. We will provide a comprehensive explanation of the entire code, detailing how these sensors work together to enable the car to detect and track your hand's movement. The various functions and behaviors of the car in response to hand gestures will be thoroughly described. Finally, the project will be demonstrated on the floor, showcasing the car's ability to intuitively follow your hand.
