Project Title
Abstract
The project will use an Android application to determine how much liquid a syringe pump outputs. The application will communicate with a Bluetooth module attached to the SJSU One board which will control the stepper motor driver to determine how many steps the stepper motor will take on the syringe pump.
Objectives & Introduction
Show list of your objectives. This section includes the high level details of your project. You can write about the various sensors or peripherals you used to get your project completed.

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.
| Week# | Start Date | End Date | Tasks | Status | Result |
|---|---|---|---|---|---|
| 1 | 4/7 | 4/9 | Order Parts | Completed (4/20) | It was much more challenging to order the 3D parts than expected. |
| 2 | 4/8 | 4/15 | Create Block Diagram, Flow Charts, Pseudo Code, Schematic | In Progress | The schematic is completed, but the flow charts and pseudo code have been delayed because of parts. Bluetooth programming was moved forward. |
| 3 | 4/16 | 4/22 | Build syringe pump and work on stepper motor programming | Completed | Parts are getting delivered and they all will arrive by the 26th of April. |
| 4 | 4/23 | 4/31 | Work on bluetooth communication between SJ one board and Android device | Completed (4/30) | Bluetooth module was easy to purchase. We moved forward with writing the Android application. |
| 5 | 5/1 | 5/8 | Work on Android device control for syringe pump | In Progress | (5/1)We have a list of options for users to decide how many steps they want to take with the stepper motor, but we have no correlation with an amount of liquid dispersed yet. |
| 6 | 5/9 | 5/16 | Test syringe pump for accuracy and Android device control | Not Completed | Not Completed |

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.
Android Application design will consist of finding a bluetooth device screen and then allows user to enter amount of liquid to dispense
SJSUOne Board will have a bluetooth task that will wait for bluetooth message, process it and send to stepper task
Stepper task will take message from que and process the exact amount of steps to output the specified liquid from syringe.
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?
