Microbit Makecode block for Adafruit Motor Driver Board.
TODO
- Add a reference for your blocks here
- Add "icon.png" image (300x200) in the root folder
- Add "- beta" to the GitHub project description if you are still iterating it.
- Turn on your automated build on https://travis-ci.org
- Use "pxt bump" to create a tagged release on GitHub
- Get your package reviewed and approved https://makecode.microbit.org/packages/approval
