The ultra simple to use pxt editor for Microbit (https://pxt.microbit.org/) supports sending data using the nRF51822 radio. The tool supports using both BLE and proprietary protocols. For this project that I did with my kids I used the proprietary protocol (that package, called RADIO, is loaded as a module by default) as that was the path of least effort.
For this project used:
- 2 x Microbit
- 1 x Line following buggy from Kitronik
The result of the project can be seen here (video)
If you are interested in trying the code yourself it can be found on github. There you can also fine README.md with instructions on how to use the code and how to load the code in the editor for further development.
The Microbit code framework is definitely a different world that what we usually work with. It is nice to see how smooth it is possible to make coding of a micro controller. If you or some kids in your family have not played around with the Microbit yet I highly recommend that you get your hands on one and try it out (everything you need can be bought from Kitronik for a quite reasonable price)
