What is the do your :bit challenge?

Let’s start with explaining the challenge. do your :bit is a global micro:bit challenge for 8 – 18-year-olds that tests imagination, creativity and technology skills.

Students from across the world are invited to come up with inventive solutions that are linked with the UN’s Global Goals of ‘good health and wellbeing’ and ‘climate action’ for the chance to win some amazing micro:bit prizes!


Resources to design your own project

Do you want to take part in the do your: bit challenge from micro:bit but don’t know where to start? We’re here to help!

We have partnered with Jasmine Florentine, A Mechanical Engineer & Designer, to create a series of Interactive videos focussing on the Engineering Design Process. You can watch the full video series here.

In the first episode below, Jasmine gives an overview of all the stages in the engineering process and how to follow these steps to design a project to take part in the global BBC micro:bit do your: bit challenge.

Follow along with the video at home, or you can play it to a classroom or coding club to take part as a group.


How are OKdo supporting the do your :bit challenge?

We think that this challenge is just incredible and aligns with everything that OKdo exists for.

We are super proud to be able to say that we are supporting the 2021 challenge as strategic partner and in this role, we have donated 5,000 micro:bit mini computers to young people from all backgrounds worldwide.

The 5,000 micro:bit donations from OKdo have been delivered tochildren in Africa, the Balkans, Colombia, the Middle East, rural Canada, New Mexico and inner-city locations in England and Scotland, to get them engaged in the competition, and in ongoing computer science skills and digital learning. Some donations have been received by:

  • British Council to support children in Nepal, Tunisia, and UK
  • The Design & Technology Association to support teaching in UK
  • Rainy Rivers School District in Canada
  • Ink Smith, Ontario, Canada
  • Space Science Institute in Colorado, North America
  • Code Art to support girls get into code New York City, North America
  • LoGig Tech supporting children’s learning in Ghana, Africa
  • STEAM Labs Africa, Nairobi, Kenya
  • Ataturk Vocational and Technical High School in Ankara, Turkey

Queensbridge Primary School, London taking part in the challenge as 4 cohorts of teachers from UK schools completed three days of training to receive 30 x micro:bits. The micro:bits were donated as part of the Connecting Classrooms programme with the British Council.

There will be two age categories for entry this year.

1. 8-14 year olds:

  • Submit an idea that solves a problem that works towards delivering the Global Goals and create a paper prototype to explain the idea, OR
  • Design and make a solution using the micro:bit to solve a problem that works towards delivering the Global Goals.

2. 15 – 18 year olds:

  • Design and make a solution using the micro:bit to solve a problem that works towards delivering the Global Goals.

    – Write about your solution – What have you created? Why have you created it? How it will it help your community or another community?
    – Create a paper prototype showing how your idea will work. This should be a photograph of your plans. Perhaps draw your solution with notes describing its functionality.
  • – Or a .hex file of your prototype code
  • – You may also include a video or photos of your device in action.

What format does my project need to be in?

– You need to write about your solution – What have you created? Why have you created it? How it will it help your community or another community?
– Create a paper prototype showing how your idea will work. This should be a photograph of your plans. Perhaps draw your solution with notes describing its functionality.
– Or a .hex file of your prototype code
– You may also include a video or photos of your device in action.

Do you have any project examples?

  • Alarm system to monitor underwater vandalism that causes harm to local sea-life
  • A device that prevents birds from colliding into glass windows
  • Radio animal trackers for endangered species
  • Pedometers to monitor steps taken

    These are just a few ideas from previous challenges…now we can’t wait to see what you come up with!
