1. Integrating Charity into Everyday Life Share Jar

2. Motivation 1. Why don’t we donate more? 2. What does donation currently look like? 3. How do you close the gap between donators and charitable organizations?

3. Project Goals 1. Decrease donation time and increase accessibility to physical donation locations. 2. Create a user friendly web system that is secure and scalable. 3. Implement a flexible database architecture.

4. User Experience Register a user card to access your account Press card against the physical unit Deposit change in open slot Signal sent to server to update user account with added amount Login to account Select charitiesInput donation amount

5. System Overview Physical Unit Deposits Server Web System Users Deposits

6. Physical Unit

7. Physical Unit (1) Coin Sorter and Display Units

9. Physical Unit (2) Arduino Microcontroller and RFID Reader -Wait for RFID confirmation -Connect Interrupts -Read data on clock signals -Convert values to digits -Check every 2.5 seconds to confirm that no additional change has been added Software Process MasterSlave MOSI

10. Physical Unit (3) Arduino Ethernet Shield -Connect to server -Wait for change in value -Call file to execute MySQL inserts Software Process

11. Deposits Server Upload, Insert, Process, Create -Connect to MySQL database -Insert values -Update CSV file with new inserts Software Process

12. Web System

13. RoR and Model View Controller http://courses.csail.mit.edu/6.831/archive/2008/lectures/L3-ui-software-architecture/

14. Web System (1) User System: Build and Testing

15. Web System (2) Charities, Favorites, Donations UsersCharities Favorites Donations favorite_charities charity_id belongs_to has_many

16. Web System (3) Cards, Deposits, and Connection to Server ?

17. Results -Average donation time of 7 seconds (with broken RFID) -Easy signup and registration system -Simple ways to favorite charities, and create donations -Potential for much smaller, easily installable donation units

18. Main Issues Faced -SPI setup -Arduino timing -Networking issues -MVC implementation -RFID reader inaccuracies

19. Future Work -Further implement integration testing -Connect deposits data to Rails server -Create application for mobile platforms -Begin to test in Production Mode
