Project Title
Logan The Smart Lock
Abstract
A staggering 1.4 billion smartphones were sold in 2015. An average consumer checks his or her smartphone 46 times a day, and in the US, people do this a collective 8 billion times every 24 hours. Most people at some point lose or forget to bring their key. Our Smart Home Lock system provides an alternate convenient way of access control on a user's smart phone. Smart Home Lock can simplify life and increase home security. Smart Home Lock provides a mechanism to lock and unlock your door with your Smart Phone, using Bluetooth communication with password protection. The door opens automatically when it senses motion when a person approaching from the inside towards the exit. An additional feature in the project is that a LCD at the entrance informs the user about the outside weather conditions, and gives suggestions accordingly. Another additional feature in the project is automatically activate lights when you arrive home after a long day spent away. How it unlocks: When Motion sensor detects you approaching Alternate means of entry: Bluetooth interface to Smartphone app with password protection

Schedule
Show a simple table or figures that show your scheduled as planned before you started working on the project. Then in another table column, write down the actual schedule so that readers can see the planned vs. actual goals. The point of the schedule is for readers to assess how to pace themselves if they are doing a similar project.

Hardware Design
Discuss your hardware design here. Show detailed schematics, and the interface here.
Software Design
Text-to-Speech
Hardware Design
In this section, you can describe how your hardware communicates, such as which BUSes used. You can discuss your driver implementation here, such that the Software Design section is isolated to talk about high level workings rather than inner working of your project.
Software Design
Show your software design. For example, if you are designing an MP3 Player, show the tasks that you are using, and what they are doing at a high level. Do not show the details of the code. For example, do not show exact code, but you may show psuedo-code and fragments of code. Keep in mind that you are showing DESIGN of your software, not the inner workings of it.
Implementation
This section includes implementation, but again, not the details, just the high level. For example, you can list the steps it takes to communicate over a sensor, or the steps needed to write a page of memory onto SPI Flash. You can include sub-sections for each of your component implementation.
Testing & Technical Challenges
Describe the challenges of your project. What advise would you give yourself or someone else if your project can be started from scratch again? Make a smooth transition to testing section and described what it took to test your project.
Include sub-sections that list out a problem and solution, such as:
Issue #1
The current was not enough from the SJOne board to unlock the Electric Door Strike. We have used 12V battery and relays to give sufficient current in order to enable the circuit.
Issue #2
Bluetooth Issue
Conclusion
This project was so much fun to work on. The project has increased our knowledge in both hardware and software know-how. We have interfaced PIR sensor, Text-to-Speech module and designed a mobile application to communicate over bluetooth. We got hands-on experience with the UART and Wireless communication. This project has provided an opportunity to delegate and work in a team. We defined our own objectives, overcame the challenges and successfully completed the project.
