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.

Rock, paper, scissors

Rock, paper, scissors is a very popular game; almost all of us play it with friends. We can make three gestures with our hands – that is, rock, paper, and scissors. Every gesture can overpower one of the other two gestures and can be defeated by another. Two users will display a random gesture, and the following rules decide the winner:

  • Rock can kill scissors but is wrapped in paper
  • Paper is cut by scissors but can cover rock
  • Scissors can cut paper but are broken by rock
  • If both gestures are the same, then it is a tie

For coding, we will assign integers to these three gestures and use conditional statements to decide the winners.

We have used the following codes and image icons for the gestures:

  • Rock = 0 and displays a square
  • Paper = 1 and displays a heart
  • Scissors = 2 and displays scissors

We will also display three different outputs on the screen based on the game’s outcome. We select the pre...
