Ops Manager Extension: Line Follower Explained

7. Experiment: Lighting Conditions

Do you think the sensor’s readings can be affected by being in sunlight or shade. What about being in the dark?

Using white card, repeat the above experiment

          • in direct sunlight (where possible)
          • in a shaded area
          • in the dark (or quasi-dark)

Use a blanket or newspaper draped over the robot to simulate darkness.

Record the average values reported in a table like the one below.

How does light affect the readings? Can the line sensors see in the dark?
