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.

Exploring the Filesystem

In the previous chapter, we worked with push buttons, slide switches, buzzers, and stepper motors. We used them with the Micro:bit and MicroPython. This chapter is a little bit of a detour from the hardware components we have been exploring.

This chapter focuses on the filesystem of Micro:bit. We will fully explore all the functionality and use cases pertaining to the filesystem. Here is a list of the topics we will cover in this chapter:

  • Creating and reading files
  • Appending a file
  • Creating our own library
  • The OS module
  • Working with MicroFS

Let’s explore working with files with MicroPython and Micro:bit.
