5.6 5. Play with Obstacle Avoidance Module
Two infrared obstacle avoidance modules are mounted on the front of the car, which can be used to detect some close
obstacles.
In this project, the car is allowed to move forward freely, and when it encounters an obstacle it is able to avoid it and
continue to move in other directions.
Required Components
In this project, we need the following components.
