Project Title
Logan The Smart Lock
Abstract
An LED display system is designed to visualize audio frequency spectrum. The system designed, can display audio frequencies by taking LED Matrix to display. The audio is sampled through an audio amplifier. The signals will be converted by integrated ADC module in the LPC1758 micro-controller. The FFT algorithm is used to convert the value from time domain to frequency domain. Extracted frequency samples are manipulated to get power spectrum and will be given to LED matrix display through I2C interface. The LED matrix display will light up row and column LEDs depending on the spectral component present in it. The features of this project are listed below:
1. LPC1758 SJOne board is used perform the Fast Fourier Transform(FFT). It takes input from the audio module and uses ADC to convert to digital signals as input of FFT module.
2. The I2C bus is used to write LED matrix board to display.
3. The audio input module takes in audio and removes the disturbances. Then this data is passed to the SJOne board.
4. The LED matrix I2C is interfaced on the SJOne

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.

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 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:
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?
Project Video
Upload a video of your project and post the link here.
