Locked: final project

Parts List:


Locked is a device that measures the distance from a sensor to the locked position of a deadbolt and informs you if your door is secured. It is a cheap and fast way to set up a customizable lock detection system to old doors and buildings.

  1. Hi Jane, like we discussed previously a great alternative to pla for making a box is basswood. Just make sure to reinforce the inside of it with corner pieces and such.

  2. If you want to measure distance, ultrasonic detection will be better. It is also very efficient to use a Hall detector to detect whether the door is closed. Install it on the side of the door.
