Project Title: Secret Knock Detecting Door Lock
Project creator: Steve Hoefer
Short description: If the user does the correct knock, the door unlocks. You can reset the knock sequence as well, and use the new lock to unlock the door as well.
Response: This seems pretty cool because it takes something that I wouldn’t think would be interactable- door knocks- and makes it so. Knocking to unlock a door would not be a good way to keep what you’re locking secure however, due to the fact that others around you could hear your knock as well.
A solution to that would be to not have it operate as a lock- maybe make a game where the arduino plays a knocking rhythm that the player has to repeat, and the rhythm gradually gets longer and longer as the player gets the knocking rhythms right.
