功能键3(Function Key 3)CMD_FUNC3
功能键4(Function Key 4)CMD_FUNC4
功能键5(Function Key 5)CMD_FUNC5
功能键6(Function Key 6)CMD_FUNC6

According to the above table, for different motherboards to write the serial port receiving procedures

When the serial port receives the message, the specific instruction judgement

The serial port baud rate is 115200

Take Microbit for example

Note the use of "text containment" for judgements


Example: Example of car:

Take mPython Board for example

The programming environment is Kittenblock, of course, with other programming platforms, it is possible to write the corresponding serial port receiving program. When receiving the command from the corresponding serial port, the corresponding motor movement will be controlled. image.png
