4. System Specifications
An ideal system/solution must possess the following characteristics:
Detect every move/changes on the board accurately
Identify different types of pieces
Verify eligibility of recorded move
Indicate illegal moves
Fast response time (<2s)
Standard sized (5cm-6cm squares) (3.75in king height)
Reflect opponent’s move clearly

7. Proposed MDR Deliverable
Detection of piece movement within a 3x3 grid and transmitting information to a mobile phone. Assembly of LED and Sensor Array(David, Battsooj)
Software Skeleton and Arduino(Shashwat)
Demonstrates:
Accurate detection of unique piece ID
Detecting the removal and placing of all 9 pieces within a 3x3 grid with minimal interference between squares
Relaying location and piece information to an Android Application through bluetooth protocol

8. MDR Accomplishments: Communication Protocol
Communication between Phones occurs through WIFI
Communication between Chessboard and Phone will occurs through Bluetooth using HC-08 with Bluetooth 4.0 Compatibility; BLE
Communication between clients and a free hosted Google Cloud Console server

9. MDR Accomplishments: Sensing System

SPI

10. MDR Accomplishments: Sensing System
Standard sized board and chess pieces
Single RFID Range Test
Worst Case Scenario
Pawn at edge of square
Increased Gain
3mm to 2mm

12. Switch from Arduino to ARM LPC1769FBD100
CDR: Microcontroller
Switch from Arduino to ARM LPC1769FBD100
512 kB of flash memory, 64 kB of data memory, Ethernet MAC, USB Device/Host/OTG, 4 UARTs, 3 SSP/SPI, 3 I2C, I2S motor control PWM
2 times more functionality than ATMega32 and will provide room for project to continue to grow

13. CDR: Android Application/ Microprocessor
illegalMoveDetection()
Engine to assess legality of moves before sending to opponent’s android application.
ledController()
Controls LED individually addressable LEDs to light in each row. Will help in reducing the number of traces on PCB
gameLogic()
checkmates, draw conditions, three-fold repetitions, and castling problems
chessBoardUI()
Design simple to use UI to display moves
findNewGame()
Access to database of players searching for new games on server
