The microcontroller is programmed in satasheet apr9600 datasheet way that depending on the satellite information of location the predefined location name will be announced. GPS based blind man device with user input interfacing voice based intellectually finds the current location and apr9600 datasheet the alert to the blind man if it was his destination area.

When using a double sided board we appr9600 consider which traces should be on what side of the board. We just have to make sure that the distance apr9600 datasheet the two locations is greater than meters. All normal C data types are supported along with pointers to constant arrays, fixed point decimal, and apr9600 datasheet of bits.

The replayed sound exhibits high quality with a low noise level.

The locations apr9600 datasheet are pre recorded in the voice circuit and are announced when the person reaches those particular locations. PIC compiler is a software in which the machine lan- guage code is written and compiled. Sampling apr9600 datasheet for a 60 second recording period is 4.

While both the buttons are pressed, apr9600 datasheet hear a beep sound from the speaker, indicating that we can release the push but- ton. Not only datashset a proper PCB neater but it is also more durable as there are no cables which can yank loose. The working of the apr9600 datasheet can be divided into two phases. In parallel access mode, sound can be rec- orded in 2, 4 or 8 sections.


Qpr9600 IC can be controlled simp- ly using push button keys. If a lot of parts are being used apr9600 datasheet a small space it may be difficult to make a single sided board without jumpering over traces with a cable.

Since we are using eight se- lection buttons in this system we can record eight differ- ent voice messages. When we finish recording, the selection button is released. Release the restart button after 1sec iv. When making a PCB we have the option of making a single sided board, or a apr9600 datasheet sided board. Once the machine code is converted into a hex code, that hex code has apr9600 datasheet be dumped into the microcontroller and this is done by Proteus.

The above disadvan- tage can be removed by using a higher efficiency GPS receiver. A double apr9600 datasheet board is more expensive to produce professionally, more difficult to etch on a DIY board, but makes the layout of components a lot smaller and easier.

When the satellite apr9600 datasheet is receieved by the GPS, the apr9600 datasheet and longitude of the current location is displayed on the LCD. This microcontroller has a program in it written in such a way that it accepts the hex file from the PIC compiler apr9600 datasheet dumps this hex file into the micro- controller which is to be programmed. Apr9600 datasheet when the blind person enters these regions loca- tions with this system the voice module will announce the location names as we had recorded them with respect to the stored locations.

The working of the system incorporates two stages; first the location based audio recording stage and second, the navigation of the blind person using the signal apr9600 datasheet the GPS receiver. Gener- ally, we put power traces on the top of the board, jump- ing only to the bottom if a part cannot apr96600 soldered onto the top plane like a relayaprr9600 vice- versa.

In this system, the GPS receiver and the control buttons are the input modules to the microcontroller while apr9600 datasheet Voice module and the LED indicators are the output modules to the microcontroller. Apr9600 datasheet project can be extended by incorporating a GSM module.


Single sided boards are cheaper to produce and easier to etch, but much harder to design for large projects. Bread- boards are great for prototyping equipment as it allows great flexibility to modify a design when needed; apr9600 datasheet er the final product of a project, ideally should have a neat PCB, few cables, and survive a shake test.

There is a simple process involved in recording these eight messages. This software is used for designing the circuit. The term is most commonly applied to electrical energy supplies, less often to mechanical apr9600 datasheet, and rarely to others. The IC can operate in one of two modes: The program which is to be dumped into the microcon- troller is edited, compiled and executed. The second phase deals with receiving the signal from apr9600 datasheet GPS receiver and actuating the voice module using the microcontroller.

PIC16F is a 40 pin microcontroller. Apr9600 datasheet this it can trace out the distance from the destination and pro- duce an alarm to alert the user in advance. The system designed consists of a GPS receiver and a voice circuit which is interfaced to the microcontroller. However, by apr9600 datasheet an oscillation resistor, a sam- pling rate as high as 8.


Doing so, we can track the movement of the Blind person in a very efficient manner. After compilation, the machine source code is converted into hex code which is to be dumped into the datashret for further processing. Apr9600 datasheet consists of 8 apr9600 datasheet from C0 to C7 Port D: Abstract — GPS is employed to find the position of the user on the earth. Press the restart button iii.
