MIT App Inventor has built a set of extensions to allow apps created with MIT App Inventor to interact with a micro:bit. The micro:bit extensions are listed below, with links to documentation for each:

• Microbit_Accelerometer - access the micro:bit’s onboard accelerometer.
• Microbit_Button - receive messages when the micro:bit’s buttons are pressed.
• Microbit_Io_Pin_Simple - a simpler interface to interact with the micro:bit’s onboard pins.
• Microbit_Led - print strings and custom images to the micro:bit’s LED matrix.
• Microbit_Magnetometer - get heading/bearing information from the micro:bit.
• Microbit_Temperature - get external temperature readings (in degrees Celsius) from the micro:bit.
• Microbit_Uart_Simple - send and receive messages using the software serial port (UART) interface for the micro:bit. This can be used to send messages to custom software installed on the micro:bit.
