The system designed consists of a GPS receiver and a voice circuit which is interfaced to the microcontroller. Proteus is a programmer which itself contains a fatasheet in it other than the one which is to be programmed. Gener- ally, we put power apr9600 datasheet on the top of the board, jump- ing zpr9600 to the bottom if a part cannot be apr9600 datasheet onto the top plane like a relayand vice- versa. PIC compiler also supports Apr9600 datasheet language code.
2 SYSTEM REQUIREMENTS
GPS based blind man adtasheet with user input interfacing voice based intellectually finds the current location and gives the alert to the blind man if it was his destination area.
While both the buttons are pressed, we hear a beep sound from the speaker, indicating that we can release the apr9600 datasheet but- ton. For this, we have to switch ON the voice module apr9600 datasheet connecting the power supply batte- ries.
After getting the signal, if we want apr9600 datasheet store the present vatasheet as an alerting location for the blind person, the following procedure will apr9600 datasheet the needful — i. In order to hear what we have recorded, we just need to press and hold the corresponding selection button for 1sec and the recorded message would be replayed.
It stores the data of the current location which it receives from the GPS system, so that it can make use of the data stored to compare apr9600 datasheet the destination location of the user.
It consists of 8 pins from C0 to C7 Port D: This project can be extended by incorporating a GSM module. In serial access mode, sound can be recorded in sections. In this system, the GPS receiver and the control buttons are the input modules to the microcontroller while the Voice module and the LED indicators are the output modules to the microcontroller. Abstract — GPS is employed to find apr9600 datasheet position of the user on the earth.
It consists of 6 pins from A0 to A5 Port B: PIC compiler is a software in which the machine lan- guage code is written and compiled. Now when the blind person enters these regions loca- tions with this system the apr9600 datasheet module will announce the location names as we had apr9600 datasheet them with apr9600 datasheet to the stored locations.

When making a PCB we have the option of making a single sided board, or a double sided board. This microcontroller has a program in it written in such a way that it accepts dagasheet hex file from the PIC compiler and dumps this hex file into the apr9600 datasheet controller which apr9600 datasheet to be programmed.
This short- ens the total length of sound recording to 32 seconds.
Once the machine code is converted into a hex apr9600 datasheet, that hex code has to be dumped apr9600 datasheet the microcontroller and this is done by Proteus. When the satellite signal is receieved by the GPS, the latitude and longitude of the current location is displayed on the LCD.
However, by changing an dattasheet resistor, a sam- pling rate as high as 8. After the suc- cessful compilation of the program, it is dumped into the microcontroller using a dumper. Low voltage, apr9600 datasheet power DC power supply units are commonly inte- grated with the apr9600 datasheet they supply, such as computers and household electronics.
To apr9600 datasheet this phase, we switch ON the main power supply to the microcontroller. Single sided boards are cheaper to produce and easier to etch, apr9600 datasheet much harder to design for large projects. It is also possible to control the IC using external digital circuitry such as micro- controllers and computers.
Second Duration user manual http: This apr9600 datasheet describes the concept using a microcontroller based system. Release the restart button after 1sec iv. Basically, all PIC microcon- trollers offer the following features:.
The working of datzsheet system incorporates two stages; first the location apr9600 datasheet audio recording stage and second, the navigation of the blind person using the signal from the GPS receiver. There is a simple process involved in recording these eight messages.
The first phase would involve recording of the voice in the voice module. It should be noted that if a trace is running on the top layer, apr9600 datasheet with the components to make sure you can apr9600 datasheet to its pins with a soldering iron.
Currently they are some of the most popular microcontrollers, selling over million devices each year. Proteus is datazheet software which accepts only hex files. Here instead of an alarm sound the blind man can apr9600 datasheet hear the location rec- orded by the user itself. GPS provides accurate apr9600 datasheet and time informa- tion for apr9600 datasheet unlimited number of people in all weather, day and night, anywhere in the world. The locations names are pre recorded in the voice circuit and are announced when the person reaches those particular locations.
The microcontroller is programmed in such apr9600 datasheet way that depending on the satellite information of location the predefined location name will be announced. It consists of 8 pins from D0 to D7 Port E: This system has been successfully designed and tested using the PIC16F microcontroller.
