Parts List & Cost
Give a simple list of the cost of your project broken down by components. Do not write long stories here.
Design & Implementation
Key Locator
Hardware Design
A in-built Nordic wireless is used for board to board communication.The transceiver used is nRF24L01+ Single Chip 2.4GHz Transceiver. Figure() shows the connection of the transceiver with the SJ One controller.
<Figure should appear here>
The boards communicate via 2.4 GHz RP-SMA Duck antennas. Figure() shows the connections of these antennas.
<Figure should appear here>
Hardware Interface
The hardware interface is fairly simple. A small 5V battery powers key via its on board 5V pins.The antenna is connected to the SJ One board via its SMA connector.The Nordic wireless has the following connections with the controller. SPI bus is used for communication between them.

Software Design
The software design is divided into two parts:
1) Key Transmitter : A Free-RTOS task is used to detect key press by the user.
2) Key Receiver : A Free-RTOS task is used to detect signal received on the Cane.On receiving the signal, a call is made to the sound buzzer.
Implementation
<Figure containing steps will appear here>
GSM Module
This module consist of a GSM/GPRS Sim900 module and a press button (panic button) mounted on the stick. In an emergency situation, the stick owner must press this button which will send an SMS to a registered user to take care of the blind person.
Hardware Design
The hardware design for this module includes a GSM/GPRS Sim900 module and a switch both connecting to a common SJ one micro controller.
<Figure should appear here>
Hardware Interface
The communication protocol of GSM module with the controller is through UART which requires four wires to establish a serial communication- Rx, Tx, Ground and Vcc. Figure() shows the connection of the GSM module with the SJ One controller.
<Figure should appear here>
A switch used as a panic button will be used as an interrupt to the controller board's GPIO pin, which will initiate the routine to send the AT commands to the GSM module necessary for sending SMS to a cellular phone.

Software Design
The software design for this module will include only a panic task. This task will monitor if a stick owner has pressed the panic button or not. If the button is pressed, then the controller will send a set of AT commands required to enable GSM module to an SMS mode and be able to send a desired SMS to the cellular phone.
