Alper created the ‘Deaf:bit’, an invention to support hearing impaired individuals live independently.

He said, "My friend's family is deaf. I saw the problem they were having and I wanted to develop a prototype for them. I thought how can I come up with a simple solution. When my teacher introduced micro:bit V2 features, I figured out how to do it."

The device is worn as a wristband and uses multiple micro:bits to give warnings in various situations such as when the house bell rings, a baby cries or a horn is sounded.

Alper shows us his 'Deaf:bit' design and the micro:bit.

Dang, Nguyen and Bui devised the ‘Healthcare Support System for the Elderly’. The system includes sensors to measure the health and environment of the user which can then be accessed by doctors or family. The system also features an automatic mechanism to dispense the correct dosage of medication at the correct time for the user.

The students said about their winning entry, "It will create a strong motivation for us to be more passionate about technology and computer science and encourage us to become programmers in the future."

Fatin, Wan and Ahmad created ‘Animal Foresee’ to try and reduce the amount of animals that are killed crossing roads. In their country, Malaysia, they are trying to protect elephants but they noted the device could be used to detect many types of wildlife, including tigers, elk and foxes. The device uses the micro:bit accelerometer to detect elephants near a road and the radio function to alert drivers.

The team said, "Taking part in the do your: bit challenge has inspired us to seek out problems in our world and try to find a way of solving them using technology."
