When we travel by bus ,the route of the bus is unknown to a new passenger. It mostly affects the illiterate . Identification of routes in rural areas is always difficult, having the need to ask the bus conductors to clarify the route multiple times. This makes their work harder. To overcome the above drawbacks of bus services, we introduce an automated bus service for the clarification and ease of traveling and to reduce error. This reduces the drawbacks of an existing system we are presenting a Fully Automated bus stop announcement system, which helps to achieve quick delivery without any traffic congestion. The proposed system can provide comfortable travel to the passengers.The mentioned prototype is fully implementable in a real-time system, which shows a predefined station without any delay.

PROBLEM STATEMENT

Motivation is the reason for people’s actions, willingness and goals. Motivation is derived from the word motive in the English language which is defined as a need that requires satisfaction. These needs could also be wants or desires that are acquired through influence of culture, society, lifestyle, etc. or generally innate. Motivation is one’s direction to behaviour, or what causes a person to want to repeat a behaviour, a set of force that acts behind the motives. An individual’s motivation may be inspired by others or events (extrinsic motivation) or it may come from within the individual (intrinsic motivation) Motivation has been considered as one of the most important reasons that inspires a person to move forward in life. Motivation results from the interaction of both conscious and unconscious factors.

MATERIALS AND METHODS

List of components

Hardware

ARDUINO UNO

Arduino is an open source electronics platform based on easy to use hardware and software. Arduino boards are able to read can tell your board what to do by sending a set of instructions to the microcontroller on the board. The Arduino Uno is one kind of microcontroller board based on ATmega328.

NEO 6M GPS MODULE

The NEO-6M GPS module is a well-performing complete GPS receiver with a built-in 25 x 25 x 4mm ceramic antenna, which provides a strong satellite search capability. With the power and signal indicators, you can monitor the status of the module.

RASPBERRY PI

Raspberry Pi is a series of small single-board computers developed in the United Kingdom by the Raspberry Pi Foundation in association with Broadcom. The Raspberry Pi project originally leaned towards the promotion of teaching basic computer science in schools and in developing countries.

16*2 LCD DISPLAY

liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directly,[1] instead using a backlight or reflector to produce images in color or monochrome. LCDs are available to display arbitrary images or fixed images with low information content, which can be displayed or hidden.

SPEAKER

Work by converting electrical energy into mechanical energy(motion).The mechanical energy compresses air and converts the motion into sound energy or sound pressure level(SPL).When an electric current is sent through a coil of wire ,it induces a magnetic field.

ARDUINO SOFTWARE IDE

Arduino IDE is an open source software that is mainly used for writing and compiling the code into the Arduino Module. It is an official Arduino software, making code compilation too easy that even a common person with no prior technical knowledge can get their feet wet with the learning process.

Software

• Arduino IDE
• Fritzing

PROTOTYPING

• Bread boarding (In Hardware)
• Library used (In Software) arduinoFFT.h, SoftwareSerial.h, DHT.h

Flowchart

TEST PLAN

The above figure shows Block Diagram

The GPS module decodes and computes the precise location of the satellite. This

reading is transmitted to Arduino. The Arduino read and display the saved position

and the next position wanted to display. Audio files will also be obtained from

speaker. The same is recorded using Raspberrypi. The same audio file plays at the

moment when a message signal is obtained from Arduino. The message signal is obtained when it reaches the exact location.Why we use raspberry pi because itcan hold a large number of audio signals.

Step 1 : Construct The Circuit

CIRCUIT

The circuit diagram consists of Arduino UNO, Raspberry Pi, neo 6m GPS module,16*2 LCD, speaker, and power supply .5v battery is connected.VCC and ground of the Neo 6m GPS module connected to the 5volt pin and ground of Arduino Uno. Then the Rx and TX pin connected to pin 9 and pin 10 of Arduino Uno. , where we can get the information of exact places and get it from the GPS module. Raspberry Pi and Arduino are connected by USB port and the power supply is also given to the Raspberry Pi. The speaker is working through Bluetooth.Raspberry Pi is used to store the information which is coming from the GPS module. The signal which is coming from the Gps module is read by Arduino Uno and then the information will be displayed by LCD, also the raspberry Pi receives data from the Arduino then the speaker is used to announce the exact places.
