micro:bit Global Challenge

Submit your idea by 17:00 (GMT) 16th November to win a trip to London!

Can you help solve a problem in your community using the BBC micro:bit?

You could win an all expenses paid trip to London to take part in an amazing micro:bit Global Challenge day and start to make a real difference in the world!

The challenge

The Sustainable Development Goals or Global Goals have been created to reduce inequality and to create a world that is fair for everyone, where no-one is left behind.

We want you to think about how you can help achieve goal 3 (Good Health and Wellbeing), 4 (Quality Education), and 16 (Peace, Justice and Strong Institutions) by focusing on the themes non-communicable diseases and safety.

How can we ensure that people stay healthy and choose healthy lifestyles? How do we make sure all communities are safe for people to carry out their jobs and attend school?

If you want to find out more about the themes, take a look at our teaching resources.

Get creating

Using the BBC micro:bit, we want you to design and make a solution to a problem that affects you and your community or another community somewhere in the world?

This could be a device that will encourage people to get active and stay healthy. A recipe plan to get your family eating well. Could you help people decide which exercise would suit them best?

Or perhaps you and your friends need some more lights for your bikes that start working when the sun sets? Is crossing the road a problem at your school? Could there be a system that helps make it safe? Is there a device that helps prevent bullying at school?

Whatever the issue, we're interested to hear how you would go about solving it. The micro:bit can do so many things so use your imagination and be as creative as possible!

Don't worry if the problem you want to work on seems small. Remember that small changes can have a big impact!


We’ll be picking 6 winners from all over the world to join us on an all expenses paid trip to the Global Challenge finale event in London, UK. You’ll meet the other winners from around the world, work on some incredible micro:bit challenges and hear from some inspirational speakers on how you can help achieve the global goals. And if you're a winner based in London and so won't need to travel, we're planning something extra special for you.

Meet the judges

Kas gali dalyvauti?

The competition is open to young people across the world aged 8-12. You may work in a team or as an individual on the challenge.

Unfortunately only one person will be able to travel to the Global Challenge finale event so make sure you discuss this with any team mates in advance.

The competition is free to enter and you don't even have to have a micro:bit to take part. If you’ve got an idea, put it down on paper or use the Let’s Code page. We’ll accept photos of your plans too.

For full competition details and rules, please read the Terms and Conditions.

How to enter

  1. Get creative and get coding! Plan your solution and design your micro:bit device.
  2. Complete an entry form and submit your entry.

You will be asked to submit:

  • Contact details – including your teacher/supervisor and parent/guardian’s details. You will also need your parent/guardian’s consent.
  • A written submission – what is your solution for – a NC disease or safety? Tell us what you have created, why you have created it, who is it for and how will it help your community or another community? (no more than 500 words).

    Or, a paper prototype showing how your idea will work. This should be a photograph of your plans. Perhaps draw your solution with notes on how it will work.
