This module adds line-following capability to your MiniBit robot!
It can sense the difference in reflectance between a line (little reflectance) and the background (high reflectance). It is equally at home with black lines on white backgrounds and white lines on black ground.
The module includes three line follower sensors instead of the usual two, so it's easier to create robust line following code. This module is easily connected to the MiniBit using the 5 screws provided.
We recommend printing your line from the patterns at RobotSquare. Alternatively you can use black insulation tape or even a black permanent marker (note that some marker pens, even though they are black, can reflect significant infrared light)
The MiniBit Makecode extension supports this line following module and you can check the current state of each sensor as well as viewing event triggers when any of them change status (eg from "Line" to "No Line").
