BBC Micro:bit in Practice

By: Ashwin Pajankar, Abhishek Sharma, Sandeep Saini

Overview of this book

This book is a one-stop guide for learning BBC Micro:bit with MicroPython, exploring many hardware components and programming techniques to provide detailed insights into developing practical applications with the Micro:bit. It will also show you how hardware components can be manipulated using a combination of Micro:bit and MicroPython for developing practical projects. BBC Micro:bit in Practice will help you gain a holistic understanding of the BBC Micro:bit platform and MicroPython programming, guiding you through mini projects aimed at developing practical knowledge of circuit design and writing programs. You’ll learn how to write programs for working with built-in LEDs and buttons, interfacing external LEDs, buttons, motors, buzzers, and much more. You’ll also work with built-in radio, speakers, accelerometer, and a compass. You’ll dive into concepts related to the Micro:bit filesystem, interfacing external displays, and working with libraries in detail before exploring sewable circuits and wearable technology. After reading this Micro:bit book, you’ll understand how to apply principles in electronics and MicroPython to create interesting real-life projects from scratch.

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.
