How to download The Code
=======================

Drag and drop the .hex file directly onto the MicroBit motherboard.
-------------------------------

Connect your micro:bit drive to your computer via USB, click the computer icon, and drag and drop the prepared .hex file directly into the micro:bit drive.

Download online via MakeCode
--------------


What is MakeCode?
^^^^^^^^

MakeCode is a free graphical programming platform developed by Microsoft. It teaches programming basics to children and beginners by dragging and dropping blocks. It is mainly used in conjunction with educational hardware such as micro:bit and Circuit Playground. It supports real-time simulation and JavaScript/Python code conversion and is widely used in maker education in primary and secondary schools.

How to use MakeCode
^^^^^^^^
1. Connect the micro:bit to your computer via USB, click the computer icon, and then click the URL on the micro:bit drive to access the programming interface.

Import makecode graphical library
^^^^^^^^

If you choose to program the car yourself, the blocks that come with MakeCode may not meet your needs, in which case you will need to import extension libraries.

1. Click the "Expand" option in the module area.
2. In the pop-up window, enter the URL of the extension library to be imported in.
   To import the LAFVIN Micro:bit Smart Car Kit Library, please enter the following URL: `https://github.com/lafvintech/LAFVIN_MBIT.git <https://github.com/lafvintech/LAFVIN_MBIT.git>`_
3. Click to expand the library: LAFVIN, and you can use the blocks in this library to program the car.
