In this tutorial, we will control the Maqueen robot using the Micro: bit card and a smartphone.
We create two programs: a mobile application with App Inventor for the smartphone and a makecode program for the Micro: bit card.
Here is the makecode program which allows you to connect the Micro: bit card to the smartphone and to receive a message containing the command order of the Maqueen robot.
We create a mobile application called ‘commander_maqueen’ with App Inventor which allows the Maqueen robot to be controlled by the smartphone.
We propose to create the design of the application, with the following visual:
To program the application, App Inventor offers us to use the Blocks space, which allows you to create a program in the form of a block diagram. Very easy to use but requiring a little programming logic.
Here is the program of the application created in the Blocks area of the Inventor App:
