This short yet intense chapter focuses on networking multiple (a minimum of two) Micro:bit devices together to exchange data between them. We will also create a few simple games that demonstrate the radio communication capabilities of the Micro:bit. The following is a list of topics that we will explore in this chapter:
- A wired network with GPIO pins
- Working with radio
- Basketball using Micro:bit ...
