In this lesson we have worked with two different sensors, the light sensor and the color sensor, and compared them in a PID line following context. We succeeded in getting the LEGO car to follow a line with both sensors by implementing a standard PID regulation and fine tuning the control parameters through a GUI. However our results show that the light sensor performs better than the color sensor due its ability to cope with physical changes like lighting in the room and vertical variations in the surface which leads to more stable readings.
