Abstract – Android platform is a new generation of smart mobile phone platform launched by Google. Android and Bluetooth technology provides the support of tourist guide system, which is probably a concern of vast numbers of developers. In our app, we develop a tourist guide system which provides the information about the place of the particular city Android based self-help guiding system with text and audio visual information using Bluetooth & android technology is an essential whenever we are visiting a particular city It gives us the valuable information about the city and saves the time. Our project gives the information about every place in the city without taking the help of any personal guide. You can search a city for its prominent places of the city user, and can get social and political information of the city, city culture, security, entertainment, Business, Hotels, Jobs etc This app contains the details of hotels, restaurant, malls, hospitals, police stations, historical places and temples. You can view all the information which is in attractive image view. This information is very useful for the one who need to know about the particular city.
Keywords: PIC16F628a-E/P, memory unit, Bluetooth, android technology.
In many tourist places, guides are not available to provide the information of that tourist place so to help tourist about direction and to provide information this project will be very useful. Also if any tourist comes in a city for first time then he is not aware of every place to be visited nearby that city. Also he is not aware of Lodges, Hotels, hospitals, police stations etc. in the city so to help those tourists. Also visually disabled persons are not able to read the information provided in text format so to help them audio format is also added. By the market survey finding this system is currently available in the market they are as follows:
Web Based Information System for Tourism Resorts With the World Wide Web, people have access to more tourism information than ever before. However, too
much information from too many sources has caused an
information overload. Accessing information on the Internet has become less a question of determining
whether the information is out there, but rather, in what form, and how to find it
Tourism Information System Based On Gis
From the geographical information system concept, discusses the main contents of the geographic information system, and the current of the geographic information system key technological measures of tourism information system, the application of tourism information system for specific requirements and goals, and analyzes a relational database model based on the tourist information system in GIS application methods of realization.
Audio Based Information System
In the big museums like Salarjang Museum in Bangalore, they have provided pre-recorded devices with audio clip and numeric buttons on it. Each article or picture placed in there is having a number written on it. User is supposed to press button on device which is displayed on article. The respective audio clip to that number is played in the device & user is supposed to hear it through headphone. While going outside, user is supposed to return it to the authority.
In this situation authority is supposed to give their valuable property i.e. device to user with keeping some deposit. This will increase the risk of the authority by two means. First is to keep eye on each user while going out, and second is responsibility of peoples deposit amount. Also investment in the device is much more.
In our system we are placing the Bluetooth device on the article or picture or the place whose information is to be given. Device will be low in cost.SD Card is used as Memory unit to store the information of the same place. It will be in Text, Audio & Video Format. Microcontroller unit reads the information from memory unit and sends it to Bluetooth module which will then transmits it to auto paired device. Bluetooth module Auto pairs with the mobile Bluetooth which is having our app. It will automatically disconnect once information transmission is done so as to connect to next mobile device in range.
GPS system detects the locations at which our auto guiding system is installed and through our app it guides the user to selected destination. Mobile units equipped with our app will only have the access to auto guide system, others are not.

Range of Bluetooth
Bluetooth 1.0 can link up to eight devices within a radius of about 33 feet with a capacity, or bandwidth, of 700Kbps. A later revision of the Bluetooth specification, Bluetooth 2.0, can transmit at up 2.1Mbps within a radius of about 100 feet. Bluetooth 3.0, adopted in 2009, increased bandwidth to 24Mbps, while the Bluetooth 4.0 specification, adopted in 2010, has a theoretical range of up to 200 feet. The Bluetooth specification stipulates a minimum range of 33 feet, but the maximum range is determined only by the output power of the device. The maximum range you can expect to achieve from a Bluetooth connection varies widely with several parameters:
> The quality of the transmitter, and the transmit power of the system
> The sensitivity/noise floor of the receiver
> The quality of the antenna being used, and whether theyre Omni-directional, or highly directional
> the test environment (out doors on a clear day with direct line of site from both Bluetooth devices and relatively high off the ground, or in an apartment
building with several feet of concrete and steel between devices, as well as interference from Wi-Fi).
> The version of the Bluetooth standard that youre using. Bluetooth 5 offers a mode of operation that can increase the overall link range. All of these parameters impact the link range of the Bluetooth connection, making it very challenging to estimate the maximum distance over which you can use Bluetooth.
ABOUT BATTERY BACKUP
PIC Microcontroller projects are clock projects. All of my clocks are powered by 5V DC wall wart adaptors. In case of power failure, the clocks stop and I have to set time when the electric power is restored. This problem will not happen with the clocks using DS1307 RTC as it provides battery backup capability. However, the clocks without DS1307 or any other RTCs will suffer from power failure. The circuit below is an example of the use of battery backup circuit with PIC16F627A or PIC16F628. The circuit can be used with other Microcontroller chips as a battery backup source. It also provide power failure signal (active low) for further processing.
As a pocket portal to the Finnish caves, this self-help mobile guide app is rather simple in the framework and easy to use. It shall meet the needs of caves information outreach and mobile interpretation. An outsourced centralized management center to develop, operate. A complete evaluation of the app effectiveness and a detailed mobile visitor studies will follow the deployment to identify and adjust to caves further needs.
Any accomplishment requires the effort of many people and this work is no different. I find great pleasure in expressing my deep sense of gratitude towards all those who have made it possible for me to complete this project successfully. I would like to thank my guide Mrs. Warsha Kandlikar for her inspiration, guidance and support.
