Leestip: Networking with the micro:bit

This book presents a series of activities to teach the basics of computer networks. While you will not
learn all aspects of computer networking, we hope that it will serve as a good starting point.
To network micro:bits, we use custom micro:bit radio to radio communication. When one hears the
word radio, what comes to mind is the radio that blasts out tunes from your favourite radio broadcasting
channel. But, a radio, or a radio transceiver (transmitter/receiver), is used in communications to
generate and receive radio waves that contain information such as audio, video or digital data. And
all micro:bits have built-in radios1

Each chapter presents interesting challenges in radio communications and networking with micro:bits.
After every few chapters, there’s an exciting game to look forward to! In the programming sections,
you will use the JavaScript Blocks Editor at https://makecode.microbit.org/ to develop solutions to
overcome those challenges2

Writing this book, we have assumed no knowledge of radio communications or networking.
However, we assume that you have written programs with a micro:bit. For example, we expect that
you are familiar with variables, if-then-else statements, and loops. The activities in each chapter will
provide ample opportunity to put this knowledge into practice.
