In this tutorial, we will control a car 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.
For the assembly of the car you can see the following article: https://www.robotique.tech/robotics/development-of-a-remote-control-car-with-microbit/
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 car.
We are going to create a mobile application called ‘commander_voiture’ with App Inventor which allows you to control the car from 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:
