Students program micro:bit to encourage physical activity

24 Sep 2021

Students Emma and Aoife from Ireland created and coded a winning tech solution to encourage physical activity and limit screen time

“Exercise is key” makes use of the BBC micro:bit’s accelerometer or movement sensor, and rewards physical activity with 15 minutes of screen time. The girls identified that using the micro:bit allowed them to make their creation small, and therefore practical for the user. This innovative product design is the winning entry in the 2021 15 to 18-year-old category for Europe. It relates to the UN Global Goal 3, Good health and well-being.

I am shocked and delighted about winning the challenge in my region!

The do your :bit challenge is an annual competition which sets young people the challenge to innovate and design solutions relevant to the impacts of the Global Goals that are meaningful to them.

Obesity and screen time is a huge problem throughout Ireland. We wanted to help improve the health of the younger generation as we believe this problem will only continue to grow if solutions are not given.
