In this lesson we are going to use the color sensor for detecting the amount of reflected light. In which cases and how would you use this setting?

Applications of the setting:

  • If we put the sensor under the robot, it can tell us when the robot moves to a different surface of the same color
  • We can use it to approximately measure the distance to an object/surface. The color sensor cannot replace the ultrasonic sensor, nor measure distance in centimeters. Nevertheless, it can tell us whether the robot is approaching or moving away from an object. The color sensor operates in a range from 1 to 5-6 centimeters – where the ultrasonic sensor cannot be applied.
