The program controls a spike prime robot equipped with two movement motors (C and D) to follow a black line on a white surface. It uses a light sensor (B) to detect the line and adjusts the robot's movement accordingly

Initialization:

• Waits for 2 seconds when the program starts.
• Sets both movement motors (C and D) to operate.
• Sets the movement speed to 30%.

Line Following Loop:

• Moves the robot forward for 1 rotation.
• Resets a timer.
• Repeats the following until the timer exceeds 3 seconds:
  • Checks the light sensor reading (B reflection):
    • If the reflection is greater than or equal to 75%, it means the robot is on the white surface (off the line). In this case, it starts moving left at a speed of -30.
    • Otherwise, it assumes the robot is on the black line and starts moving right at a speed of 30.

Stopping:

• After the timer exceeds 3 seconds, the robot stops moving
