Networking and Radio
In the previous chapter, we learned how to program the Micro:bit for producing music and speech. We learned to connect an external speaker to the Micro:bit. We also explored the built-in speaker and microphone in Micro:bit V2.
Networking means connecting two or more computers (or microcontrollers). It enables them to exchange data. 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
- Rock, paper, scissors
- Voting using the Micro:bit
Let’s get started with networking and radio communications.
