Extension URL (for importing into your projects): https://github.com/robo-technical-group/pxt-arcade-info-screens.git
The README.md with some code samples can be found at the GitHub repository:
You can see a sample of the different screens here. It works on hardware, too!

Happy Monday, and Happy Coding! Have fun!
