【題目】Changing Bit by Bit

A new contest challenges people to use micro:bit computers to solve problems.

Could you use your computing skills to aid the fight against illegal animal hunting? How about tackling ocean pollution or monitoring animals under threat of extinction?

A new global challenge called Do Your Bit aims to get young people using their computing creativity to solve real-world problems. It’s being run by a partnership involving the BBC’s micro:bit computer, the technology company ARM and a campaign called World’s Largest Lesson, and it's aimed at people aged 10 to 16. It kicks off on 16 September.

The contest in 2019 is based on two Global Goals: to protect life on land and under the water. To take part, young people first choose a problem that affects them and their community, then design something involving the micro:bit computer that could help to tackle that problem.

Participants need to write up to 500 words about the problem and their solution, as well as providing a photo of their drawn plans or a hex file of their prototype code (編碼), plus any other photos and videos showing what they’ve done.

This is the second micro:bit Global Challenge to be held. In 2018, the contest's winning designs included a homemade thief alarm, a classroom health monitor, a food-waste watcher and a device to remind people to sit up straight.

The deadline for entering the challenge is 28 February 2020: the winners will be announced the following month.

【2】The Do Your Bit in 2019 is based on the theme of________.
