Kitronik's BBC micro:bit controlled Line Following Buggy uses two LDRs (light dependant resistors) as sensors to control a line following board on the bottom of the chassis to 'follow' black lines.

Two LEDs shine light from underneath the buggy down onto the floor and a pair of LDRs measure how much light is reflected. When the sensor is moved over a black line the level of reflected light decreases and the sensor sends a signal to the BBC micro:bit through the motor driver board. The BBC micro:bit then uses that information to steer back toward the line. It does this by switching off either the left motor to turn left or the right motor to turn right.

Code for the line following function is available below. The buggy can easily be customised and to help you get started we have also supplied code for Bump 'n' Spin functionality using the BBC micro:bit's on-board accelerometer. Save the code to your account and get customising!
