Introduction
What you will do
In this 60 minute workshop you will use the
mu
editor on a Raspberry Pi to write
MicroPython programs and run them on the micro:bit.
MicroPython is a small but very fast version of Python 3 that has been specially
designed to work on microcontrollers such as those found on the micro:bit.
The experiments will show you some of the things the micro:bit can do. You can
use them as a base to build your own projects.
At the end of this workbook you will find some links to help you explore once the
workshop is over.
What you will need
You’ll need a BBC micro:bit and its USB connector. You don’t need a battery, as the
micro:bit will be powered via USB.
If you have a Raspberry Pi
This workbook assumes that you have a working Raspberry Pi with screen, key-
board and mouse, that you will connect via USB to a BBC micro:bit.
