In this tutorial we will use two micro:bits to broadcast messages to each other over bluetooth. This would be incredibly useful if teachers wanted students to code secret messages for a story, share historical facts with one another, make your own “heads up” game or even have teachers broadcast questions to students. The possibilities are really only limited by our own imagination. If I have learned anything in the last thirteen years in education, it is that students’ imaginations are much more powerful than mine! I bet they could find a really creative and authentic use for a micro:bit messaging app! Check out the tutorial below!
