What it’s about
Each, micro:bit has a built-in radio it can use to exchange data. This tutorial shows how to use the MicroPython radio module’s methods to make micro:bits exchange text. It also includes examples that change the radio channel, and a bidirectional texting app.
Before you start
You will need:
- Two or more micro:bit modules (on or off a cyber:bot)
- Two USB A to MicroB cables
- One or more computers with:
- Access to python.microbit.org
— or — - Mu editor installed
- Access to python.microbit.org
- Note that python.microbit.org/v/2 is used in this tutorial’s screencaptures.
Complete this tutorial first:
After you finish
You will be able to write MicroPython scripts that make micro:bit modules send and receive messages with their built-in radios. Your scripts will also be able to change channels to access different data streams.
After this, you will also be ready to move on to the next tutorials (coming soon!):
