Ops Manager Extension: Line Follower Explained

3. Experiment

Different colors and materials reflect different amounts of infrared light. Let’s do some basic science experiments to understand this further.

In the experiments that follow you will use a template function called test_sensor_readings() that has been written for you. This reports summary statistics based on the values read from all the line sensors on the underside.

In preparation,

          • amend the code in the Test & Calibration Code cell so that the test_sensor_readings() function (highlighted in red) is un-commented
          • ensure everything else is commented out

Click on Run Selected Cell to check that everything is in working order. You should see a response like the one below (your numbers will be different):

AVERAGE = 0.07    MINIMUM = 0.03    MAXIMUM = 0.11
