What is micro:bit board ?
The micro:bit is an electronic prototyping board that allows to program interactive projects.
It use sensors and control outputs devices like LEDs, speaker.
What can we do with the micro:bit's accelerometer ?
The accelerometer measures the board’s movement along three axes
The x-axis in red, the y-axis in green, and the z-axis in blue.
2) Let's create our first program with the accelerometer (without AI)

We want that :
If the board is shaken, sparkles appear
If the board is tilted upward, upward arrow appear
If the board is tilted to the left, left-pointing arrow appear
If the board is tilted to the right, right-pointing arrow appear
It it doesn't work : don't forget to put "CLEAR SCREEN" in the beginning ; don't nest the "if instructions".
Plug the blue board’s USB cable into the computer.
Click on this link Microsoft MakeCode for micro:bit (set the language on english if necessary)
Then click on "new project" (no need to put a name), recreate and complete the program shown above.
We can see that only a limited number of movements can be detected : tilting to the sides or shaking the board.
We are going to use machine learning so that the board can distinguish for example between waving a hand or raising a hand.
3) So now close the previous windows and click here. We will see how to improve our program with AI.
