Follow a Line (Hint)

Home > Activities > Robots > Examples

Action: Follow a line using one light sensor. More precisely, follow an edge with dark on the left and light on the right. The edge may curve either way or go straight. Fill in your own code for (Turn left) and (Turn right).

Reading the program

• Begin the program
• Begin a loop (red land)
• Read the light sensor connected to port 2
  If the value read is greater than 40:
• (Turn left) - your code here

If the value read is less than or equal to 40:

• (Turn right) - your code here
• Merge
• Loop to the red land (red jump)
• End the program

Where to find it
