Line Following Buggy for the BBC Micro:bit V2.0

The Line Following Buggy with :MOVE line following board for the BBC micro:bit is the newest version of our very popular line following buggy. It offers a significant upgrade in the form of our new :MOVE line following board. Not only does it provide far superior line following it also makes the kit much easier to assemble, making it a suitable activity for younger children.

The line following board is supplied pre-assembled, so no soldering of components is required. The only soldering required for assembly is to attach the wires to the two motors.

The board design is such that the buggy can either follow a dark line on a light background or a light line on a dark background. For best results, ensure there is approx. 5mm clearance between the bottom of the board and the driving surface.

Also, the sensitivity of the line following can be adjusted via the two onboard pots, one for each detector. The same pots are also used to change the type of line that will be followed; to detect darker, turn the pot clockwise and to detect lighter, turn the pot anti-clockwise.

In addition, although the buggy has been designed to follow lines, due to the flexibility of the BBC Micro:bit board, it can also be used as a remote-controlled robot buggy.
