In this comprehensive lesson, we will delve into the exciting process of building and understanding the functions of a self-driving car. In the previous lessons, Car-1 through Car-5, we progressively added features such as Infrared Obstacle Avoidance and the Ultrasonic Sensor, learning how to effectively drive the SunFounder Smart Car. Now, we will bring all these accumulated features together to create a car that can autonomously navigate and avoid obstacles. This advanced iteration of our smart car will not only move forward and backward, but also intelligently maneuver by moving back-left and back-right to efficiently find its path around obstructions. The underlying code will be thoroughly explained, with its logic and behavior first demonstrated via the serial monitor, followed by a live demonstration of the car's impressive capabilities on the floor. This is a very cool project that we hope you will thoroughly enjoy.
