The line sensor looks at the floor beneath it and answers yes or no. And here's the lesson that applies to all sensors: on top of the line but standing up, it can't see it, because it's not looking at it; you have to lay it down.

🎯 The challenge of this lesson

Paint a track with a closed curve and place two line sensors apart, one on each side of the center; check what each one reads when the robot goes straight and what they would read on the curve.
