F21: FollowMe
Contents
Abstract
FollowMe is a video game where you follow the correct directions. The LED matrix will display a series of arrows and the player or players need to correctly wave their hand over their gesture sensor to earn points. However, watch out for the background color of the arrow. If the background is green, then the players need to wave their hand in that direction; i.e, an arrow pointing left with a green background means wave your hand from the right to the left (wave left). If the background is red, then the players need to wave their hand in the opposite direction; i.e, an arrow pointing up with a red background means wave your hand from the top to the bottom (wave down).
There'll be two modes:
1. Timed mode: each player tries to get the most correct waves until the time runs out. The rate at which the arrows change will increase as the timer counts down.
2. Endurance mode: each player tries to stay alive the longest. One wrong wave then you're eliminated, the last player standing wins.
At the end, the LED matrix will display the leaderboard for the players and how many waves/instructions they got correct.
- Block Diagram of Follow Me needs to be added
Objectives & Introduction
Project Introduction
1.Analyse hand waving/movement using a gesture sensor
2.Connect different microcontrollers wirelessly to exchange information
3.Read a file from SD card on the microcontroller and get the MP3 data using MP3 decoder
4.Display different screens according to the game level(Title screen, Arrows and leaderboards)
Project Objectives
1. Gestor Control: APDS-9960 gesture sensor on SJ2 board should respond to hand waving. I2C interface will be used for this sensor.
2. ZIGBEE wireless: UART interface used to connect the wireless devices, which will send information to other boards.
3. MP3 decoder: MP3 data will be fetched from mini SD card reader using SPI interface.
4. 64x64 RGB LED matrix: LED will be controlled by GPIO of SJ2 board. The LED will display game graphics.
5. 3D Printed enclosure: The system will be enclosed in a 3D printed enclosure.
Team Objectives
1.Learn and understand the APIs of the Real Time Operating System
2.Use different embedded protocol to interface the system
3.Learn to design a module and interface the modules by reading datasheets
4.Integration and testing to deliver the final product
5.Track and respond to the reported bug and document the bugs and solutions.

Printed Circuit Board
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 implementations.
Testing & Technical Challenges
Describe the challenges of your project. What advice would you give yourself or someone else if your project can be started from scratch again? Make a smooth transition to the testing section and describe what it took to test your project.
Include sub-sections that list out a problem and solution, such as:
<Bug/issue name>
Discuss the issue and resolution.
LED Matrix: faulty matrix , needed to buy another one. Lessons: order the obvious component as soon as possible and test it.
- Measure the resistance between 5v and ground terminal
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.
