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
Schematic of the design
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.
- Power circuit is a series of batteries, which provides 7.5V power supply.
- Motor controller, which is the H-bridge circuit, communicates with SJone Board. When the power supply of H-bridge is between 7-12V, one of its pin can be use as a 5V power supply. H-bridge has two sets of GPIOs to control different motors. Each set has two GIPOs, one for moving forward, another one is reversing.
- SJone Board is communicating with different sensors. Including sending trigger signals to ultrasonic sensors and getting feedbacks of those sensors.
- Infrared sensor is used to detect any obstacles in front of the car.
- Ultrasonic sensors are triggered by the high pulse sending by SJone Board and gives the feedback back. We can get the distances between obstacles and the car by calculating the length of those feedbacks.
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 pseudocode 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?
