In this lesson, we will explore how to integrate and utilize the Infrared (IR) Obstacle Avoidance module with your SunFounder Smart Car. This module, an essential component of the Arduino Kit from SunFounder, allows your smart car to detect objects in its path and react accordingly, enabling it to autonomously navigate and avoid collisions. We will cover the principles behind IR obstacle detection, the necessary wiring, and the Arduino code required to implement this functionality.

Initially, we will explain the foundational code, illustrate the correct wiring, and then demonstrate the code's immediate effect. This will show how, when an object is detected in front of the car, the corresponding IR sensor (either on the right or left) will trigger, prompting the car to move in the opposite direction to avoid the obstacle. Following this, the code will be modified to incorporate a 'stop' function, allowing the car to halt when an obstacle is detected, rather than just changing direction. Finally, the complete project will be demonstrated, showcasing the smart car's ability to autonomously detect and react to obstacles.

We will cover the principles behind IR obstacle detection, the necessary wiring, and the Arduino code required to implement this functionality.

We will begin by thoroughly explaining the initial code, followed by a clear depiction of the wiring connections. Subsequently, the code will be demonstrated to illustrate how the IR sensors on the right or left of the car detect an object, prompting the car to move in the opposite direction to avoid the obstruction. We will then modify the code to incorporate a "stop" function, allowing the car to halt when an obstacle is detected in certain scenarios. Finally, the complete project will be demonstrated, showcasing the smart car's ability to autonomously detect and avoid obstacles.
