Torsten Rasmussen 1cccc8a8fe cmake: increase minimal required version to 3.20.0 Move to CMake 3.20.0. At the Toolchain WG it was decided to move to CMake 3.20.0. The main reason for increasing CMake version is better toolchain support. Better toolchain support is added in the following CMake versions: - armclang, CMake 3.15 - Intel oneAPI, CMake 3.20 - IAR, CMake 3.15 and 3.20 Signed-off-by: Torsten Rasmussen <Torsten.Rasmussen@nordicsemi.no>		2021-08-20 09:47:34 +02:00

BBC micro:bit line-follower robot
#################################

Overview
********

This sample controls a stand-alone line-following DFRobot Maqueen
robot chassis containing a BBC micro:bit board.

Requirements
************

To build and run this sample you'll need a `DFRobot Maqueen robot
chassis (ROB0148) <https://www.dfrobot.com/product-1783.html>`_
with a BBC micro:bit board. Use black tape to create a line track
for the robot to follow. Build and flash the program to the BBC
micro:bit board (described below), turn on the robot,
and put it on the black line track.

Building and running
********************

Build and flash this sample project using these commands:

.. zephyr-app-commands::
   :zephyr-app: samples/boards/bbc_microbit/line_follower_robot
   :board: bbc_microbit
   :goals: build flash
   :compact:

Sample Output
*************

The sample program controls the robot to follow a line track and does
not write to the console. You can watch this `robot video`_
to see it in action.
