Unformatted text preview: problem is not impossible to overcome with some modification on the existing microcontroller and circuit design. Another limitation of the proposed design is that the user will have to hold the door against spring force. However, the door is not going to close within 15 seconds if the user does not close it. It will stay unlocked and will not be fully closed. This somehow protects the privacy of the user because otherwise if the user leaves without closing the door other people would be able to look into the module in the first 15 seconds. 7.
