After looking over what a microbit can do, i realized that using the built in compass, not for directions, but for locating and sensing magnetism. The compass was built to locate directions, but we can also use it with magnets for security. We can put some magnets on a object and a microbit close by, so that when the object is moved, a loud sound will be played. We can also out magnets on doors so that when a door is opened, a alarm can also be played. That’s all I can think of for now, so till next time.
