Thank you for purchasing our expansion pack. This kit is designed for children aged 7-14 who have completed our ‘Fun Science Code Club Home Kit’ or who have previous knowledge of coding with the BBC Microbit and Blockly editor. Before you start, click here to join our optional Facebook group where you can request help and share your children’s creations. If you get stuck with any of the projects or activities, just email and we will be able to help you. Each activity has written and video instructions. You could use just the written instructions, just the video instructions, or a combination of both. Older children may wish to challenge themselves to just use the written instructions and have the videos just in case they get stuck. All videos are only accessible to people with the link.

Project 1 – Connecting a speaker and making tunes

– Getting started –  – This is a video from the previous projects. Good as a refresher if you haven’t used your Microbit in a little while but if you know what you are doing, move straight onto the first project! Connecting your speaker – Make sure you read this before moving onto the first coding project. Next, you will be programing a tune onto your Microbit. You can read these instructions or watch this video.
– Extra help if you are struggling to move the file over to your Microbit –

Project 2 – Making a game that uses sound

This is a brand new, two player game that you can play on the Microbit. It uses the speaker to make a tune when you win or lose. You can read these instructions or watch this video.

Project 3 – Connecting up the LED and making different colours.

This project is a bit of a long one so we’ve split it up into four different activities. You may wish to spread this out over a few days or do it all at once!
Before you do anything, read these instructions and learn how to use your breadboard to connect your LED to your Microbit.
Next, we will be testing if everything is connected and making the primary colours of light. You can read these instructions or watch this video. If your circuit isn’t working, watch this troubleshooting video to find out what may have gone wrong. If it’s still not working, send us an email to and we will help you out!
Then, we move on to making the secondary colours of light. You can read these instructions or watch this video.
Finally, you can experiment with making all sorts of different colours of light! You can read these instructions or watch this video.

Project 4 – Making a random light generator

In this project we will be letting the Microbit decide what colour of light it wants to generate and having the Microbit’s screen tell us what amounts of power it has chosen to send to each of the different coloured lights.

Project 5 – Making a flashing light

In this final project you will be making a light that flashes between two or more colours.
