pdf drop coin and get power

Abstract
Drop Coin and Get Power project is developed to control a load through coin box using microcontroller in a prepaid manner.

It consists of a Coin box, Microcontroller unit, key pad and a LCD Display. The user can add the validity of their account by inserting coins in the coin box. Their account will be updated according to the number of coins added in the box. The money value will be displayed in a LCD display.

The user can use the Electricity upto the certain limit. The user can also watch their usage le ....etc

ABSTRACT
Fuzzy logic, a relatively new cutting edge technology, is nowadays gaining popularity. Fuzzy control is a practical alternative for a variety of challenging control applications since it provides a convenient method for constructing no-linear controllers via the use of heuristic information. Such heuristic information may come from an operator who has acted as a human in the loop controller for a process. A fuzzy controller emulates human decision-making process. Fuzzy control provides a user-friendly formalism for ....etc

Intelligent Train



INTRODUCTION :

We know that the railway network of India is the biggest in south Asia and perhaps the most complicated in all over the world. There are so many different types of trains local, fast, super fast, passenger, goods.. etc. and their so many multiple routs. Although the time table is perfect it is not at all possible to maintain it. And that s why the train accidents are becoming more and more usual. So why not we add a kind of intelligence to ....etc

wireless communication is limited to certain range because there are some obstacles and communication barriers across the way. so the receiver is not able to receive the signal as it is sent from the transmitter. so we need the help of satellite.

here we are designing a satellite which receives signal from one station. it amplifies and re transmits the signal to the other station. both the transmitter and receiver uses telescopic antenna for transmission and reception.

in this section, a signal is transmitted using fm transmit ....etc

advantages of unmanned petrol bunk system using smart card

Abstract
Today almost all petrol pumps have a micro controller to control the electrical pump, drive the display, measure the flow & accordingly turn OFF the electrical pump. But still a person is required to collect the money. Our project is designed to eliminate this human interaction so that there is no need of workers to fill the petrol.
In general, a smart card is an integrated circuit card with memory capable of making decisions. This project can be used for recording the at ....etc

AUTOMATIC PRESSURE CONTROLLER

ABSTRACT
The project work entitled 'automatic pressure controller' uses PIC 16F 72 microcontroller as its main component. It is a simple and low cost circuit for sensing atmospheric pressure. It automatically senses the atmospheric pressure and displays the pressure in Pascal on an LCD Display. It also indicates the level of pressure to inform about unfavorable pressure conditions. Today microcontrollers are common, so the microcontroller based Pressure controller is flexible and reliable. ....etc
