To create our microbit censor detector we will have a detector that has LED lights. They way we plan on making this is by having a small microbit on the ground or somewhere out of sight so that when the microbit will send a silent alarm and flash a bit of colour to notify security that someone has broken in. We plan on coming in at lunch to complete and figure out the best possible way to  make this work. Hopefully we can make a detector that goes off if you dont have the key.
