Device Concept: Two detectors (micro:bit, ultra-thin rechargeable battery, name badge lanyard). Using the built-in Bluetooth radio functionality, two micro:bits communicate with each other. Primarily, the nine-axis sensor detects the relative direction and position of the two micro:bits, using LED lights to guide and quickly locate the other person. The 'A' button controls the other micro:bit to play music, indicating that they are nearby. The 'B' button triggers a beeping sound on the other micro:bit, letting the other person know they are being searched for. In addition to detecting direction, the nine-axis sensor can also monitor speed to determine if the wearer has fallen, enabling immediate assistance.
We were inspired to track missing elders and seek medical attention when a fall occurs.
This project uses the micro:bit to create an alert system that measures humidity and water depth levels near the riverbank.
This project utilizes a micro:bit to sort garbage found on beaches.
This project uses micro:bit to help detect and avoid possible discrimination.
