NotifyBox
Abstract
With the rise of e-commerce, online shoppers are receiving more mail than they ever have before. This increase in online shopping will also come with an increase of mail and packages received. NotifyBox will help consumers remotely be more aware of when packages/mail has been delivered to their mailbox. NotifyBox will provide users with a notification on their phone showing when their mail has been delivered. An IR beam will be used to check when mail is received. This will be interfaced to an SJOne board. Once mail has been detected the SJOne board will send the data to another SJOne board over wireless communication. The second board will then communicate that data over Bluetooth to a phone. Every time the beam has an interference, the user will receive the notification on their phone.
Objectives & Introduction

Parts List & Cost
| Part Name | Part Number | Quantity | Cost | Notes |
|---|---|---|---|---|
| 2x WiFi Transceiver Module 1MB Flash | ESP8266 ESP-01 | 1 | $9.95 | For interfacing WiFi |
| Xbee Bluetooth Bee | Iduino Xbee V2.0 (HC-06) | 1 | $11.99 | For interfacing Bluetooth |

- NOTE:
- Bluetooth module HC-06 only works as a slave, not as a master peripheral. Will need to get an HC-05 if you would like to perform as a master and slave.
- The Bluetooth module is also not a Bluetooth Low Energy (BLE) module. If you would like to connect to an iOS device, you need to have a BLE module.
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. //will delete before finalizing
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. // will delete before finalizing
In our block diagram, we have one infrared sensor(IR) that we will be using to determine if mail has been received. Once the IR sensor beam breaks, microcontroller 1 will receive that data. The IR sensor sends data to the microcontroller over GPIO interface. Once microcontroller 1 has the data it will package the data and then send that package to microcontroller 2 via wifi. When microcontroller 2 has received the package this will notify the user with a notification that mail has been received. The communication from microcontroller 2 to the iPhone will be done using a Bluetooth module.
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:
Issue #1
Bluetooth implementation on the iOS app was by-far the hardest part of the project. After hours, days, weeks spent on interfacing our xBee HC-06 Bluetooth module, we found that it was impossible to have the HC-06 discoverable by iOS (iPhones, iPads, iPods). Because the HC-06 does not use with Bluetooth LE, and is not MFi certified, it was considered to be not following Apple's standards, thus not allowing any HC-06 Bluetooth modules to be able to be paired with iOS devices. We had to change our approach on our objectives. We opted to use a Bluetooth terminal app in Android to talk to our xBee HC-06 module.
Issue #2
The wireless communication gave us a very hard time to transfer the data from one board to the other. Thinking that the way that we implemented it was incorrect, we were trying to fix our code for many hours. It wasn't until we decided to try to attach antennas to our SJOne Board that it then started working properly. Our issues was instantly resolved with antennas.
