1. Introduction

   1. Statement of Purpose

      We propose a smart door lock that can be set to a certain length of time before it unlocks by itself and can be controlled with your phone to add more time on the lock or unlock it early.
      
      

   2. Background Research

      One of our team member's roommate was once locked out of his room after showering because the member had left for lunch and locked the door. The member had to run all the way back to the dorm to open the door for his roommate. This experience was troublesome enough that we decided to work on a project that can solve this problem. Furthermore, we decided to improve upon this project and add a timer so the lock can be set to unlock itself after a period of time. This allows the user to not have to lock and unlock the door when leaving for short periods of time.
      We have found WIFI lock projects similar to our proposal on Youtube. Links provided below.
