How to Build a Line Tracking Robot?

Overview
In the previous projects, we have introduced the principle and application of line tracking sensor and motor
driving. We're now ready to give the Micro:bit robot an upgraded capability - Line tracking!
What is line tracking?
Line tracking is exactly what it sounds like - following the track. The robot can always stay on its black track.
How does it work?
It uses the tracking sensor to detect the black track on the pavement, and detection signal will feed back to the
micro:bit main board. Then micro:bit main board will analyze and judge the collected signals to control and drive
the motor in time, thus can adjust the robot turning direction.
