Project Title: Door Alarm System

Abstract

Our project would use a motion detector and light sensor on the SJOne board to control the output of a speaker. If the someone opens the door during daytime, the speaker would output a song as a welcome. However, if the door opened at night where there’s no light, the speaker would output an alarm because there might be thieves coming in during midnight.

Objectives & Introduction

The objective of this project to create a realizable indoor anti-theft system. The system is able to detect the people's motion by using the motion sensor, and judge the current brightness by using the on-board light sensor.

In order to accomplish the objective, we need to the following things:

> Modified the Pulse-Width Modulation(PWM) source code to allow the speaker to play a song. > Figure out how to amplify the sound signal. > Using the ADC code to receive the signal from motion sensor.

Team Members & Responsibilities

  === Bowei Zhang ===

• program the speaker.
• Programming the ADC code.
• testing the software.

  == James Huang ==  

• Improve the playing song algorithm.
• Design the hardware connection between MCU and external parts.
• Programming the ADC code

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.

Parts List & Cost

Design & Implementation

The design section can go over your hardware and software design. Organize this section using sub-sections that go over your design and implementation.

Hardware Design

Discuss your hardware design here. Show detailed schematics, and the interface here.

Hardware Interface

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 psuedocode 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:

My Issue #1

Discuss the issue and resolution.

Conclusion

Conclude your project here. You can recap your testing and problems. You should address the "so what" part here to indicate what you ultimately learnt from this project. How has this project increased your knowledge?
