4.DESCRIPTION (Description shall start from next stage.)

Description
The Fig 1 shows the block diagram of cell phone. The GSM module has provision of inserting a SIM card into it. Whenever someone calls or texts the blind person the GSM module will serially provide the data to microcontroller. Microcontroller sends AT-Commands to control the GSM module. As we know that GSM module sends the ASCII code of all the characters, microcontroller will accept those ASCII Characters and convert them into Braille codes and send it to multiplexing display. Upon reception of call or SMS an acknowledgement is provided using a buzzer. A keypad is used to type SMS or make a-call. While typing braille feedback is provided on display. User can check what he has typed and send it accordingly to GSM module using a controller. All the notifications of call and SMS are transmitted wirelessly to watch using wireless transceiver.
The Fig 2 shows the bock diagram of watch. The microcontroller will communicate with RTC to get the current time and date. Wireless trans-receiver with the help of microcontroller will communicate wirelessly with thee cell phone and bring the notification on the watch. GPS module will provide the position details and send it to watch wirelessly. Keypad is used to adjust time and date. Also it is used to set alarm. Buzzer is used to buzz the alarm and notify the user for other notifications. Braille enabled display will display the data in braille language
The figure 3 shows the interfacing diagram of cell-phone. The GSM module and RF module are connected at different serial port of Arduino mega microcontroller. The buzzer is connected to digital pins. The data to the entire matrix is made common while selection of matrix helps us to provide unique data to the entire matrix using concept of multiplexing which is based on persistent of vision. Data and enabling signal are controlled using digital pins of controller.
The Fig 4 shows the interfacing diagram for the watch. The microcontroller requests for the current time to RTC module. RTC module provides current time and then microcontroller converts the time information into braille and sends it to display. The keypad is used for date and time management. It is also used to set alarm. A GPS module provides the current position details and sends the data to cell phone wirelessly. With the help of wireless module and microcontroller, notifications on cell phone can be made available on wrist watch. The braille enabled display consists of matrix of 6 dots which is used to represent the data into braille language. Blind can use his touch sense to recognize the data.
