Maqueen micro:bit Educational Programming Robot Platform

Hello, my name is Maqueen and I am a graphically programmable robot. The mini-robot offers interesting functions and is plug-and-play. This allows children to quickly learn graphical programming to arouse interest in natural sciences and logical thinking. You can do the graphical programming of the robot with the online editor https://makecode.microbit.org where you can also find many sample codes for the robot. In order to use the Maqueen Library you first have to add the following extensions:
