MakeCode Extension for Nexus:bit

Microsoft’s MakeCode graphic editor is already powerful enough, but it also allows users to develop their own custom extension to re-packaging complex functions into simple blocks. Just click and drag those blocks and kids can do coding on them! This is why TCEA designed an extension specifically for Nexus:bit. (You can still control your Nexus:bit by using standard MakeCode blocks, not limited by our custom extension.)
(To use this extension, go to the MakeCode editor and click Advanced -> Extension... then enter "nexusbit" in the search box. Click the extension which appears to import it.)
