Sample Code

Example 1: The Robot That Avoids Light

Program Description:

• This example demonstrates that if there is strong light on one side during the driving process of the car, it will turn to avoid the light and drive.
• In actual tests, the flashlight function of the mobile phone can be used to shine on the light sensor to verify the program effect.

Example 2: The Robot That Tracks Light

Program Description:

• This example demonstrates that if there is strong light on one side during the driving process of the car, it will follow the direction of the stronger light to drive.
• In actual tests, the flashlight function of the mobile phone can be used to shine on the light sensor to verify the program effect.
  

Result

• Example 1: Car turns away from strong light.
• Example 2: Car moves toward strong light.
