My microbit project pt2

Me and  Kiara have plans to visit the tech room to be able to create the best possible way to create a silent alarm that reacts if you do not have a certain key to let you in. I would also like to add a LED light that goes of and gives a flash if you do not have the card. However our censor will be out of sight so that the robbers dont know its there. We hope this will help decrease the number of robberies and make a safer environment.
