Quiz buzzers are used often at places like educational institutions where it is required for game shows and also in live quiz competitions broadcasted via television. A quiz buzzer allows any user to press the switch quickly in response to a question posed during competitions that are conducted in schools and colleges. The pressed switch gives a buzzing sound or alarm for some duration of time and the reaction time is very small. Buzzer can also be used in different applications such as annun...
ABSTRACT The increasing rate of crime, attacks by thieves, intruders and vandals, despite all forms of security gadgets and locks still need the attention of researchers to find a permanent solution to the well being of lives and properties of individual. To this end, we constructed a cheap and effective security system for buildings, cars, safes, doors and gates, so as to prevent unauthorized person from having access to ones properties through the use of codes, we therefore experiment the a...
INTRODUCTION TO SMART CARDS It has been said that smart cards will one day be as important as computers are today. This statement contains a bit of an error because it implies that smart cards are not computers, when in fact, they are. Because smart cards are indeed tiny computers, it’s difficult to predict the variety of applications that will be possible with them in the future. It’s quite possible that smart cards will follow the same trend of rapid increases in processing power that...
ABSTRACT Energy is of great importance to the world at large. It is very important to every nation for growth and development as it is a driving wheel for technological advancement. It is to this end that good management and audit should be inculcated to make sure that this energy is utilized and sustained. This work centers on techniques and measures involved in management and ascertaining good audit. TABLE OF CONTENT Page Title page i Certification ii Ackno...
INTRODUCTION:Many interconnection device are required in a modern network, from the interface that allows a single computer to communicate with other computers via a LAN cable or a telephone line, to the large and complex switching devices that interconnect two or more entire networks.
ABSTRACT Till date IVR systems are used in the areas of telephone banking, tele-voting etc but our project is a step towards even broader aspect and usage of IVR systems i.e. in college automation. Through our project “microcontroller based automation system”, we are trying to replace the conventional notice board by a well automated device. The circuit enables the user to hear as well as read the information being announced through a speaker and an LCD.If the announcements regarding any...
ABSTRACTCharging and preserving are major issues in the services of batteries since they are mostly connected to most applications. As many batteries are charged and recharged through their uses the maximum power and capacity of the battery slowly decreases. The phenomenon is termed aging is a particular concern in fields such as the automobile industry where efficient performance and long battery life is essential. Even when the batteries are left for a long time without using them, their pe...
Abstract This seminar is designed to make home automation easy to control when a user is not at home. The paper is designed to allow easy use of a mobile phone to control appliances in the home. Using a mobile phone the development of the control system will be carried out using SMS. This will communicate with another mobile phone, which in turn controls the devices attached to microcontroller modules. When the action has been carried out then a response is sent to the user. The p...
ABSTRACT Security is a prime concern in our day-today life. Everyone wants to be as much secure as possible. An access control for doors forms a vital link in a security chain. The microcontroller based Door locker is an access control system that allows only authorized persons to access a restricted area. The system is fully controlled by the 8 bit microcontroller AT89C2051 which has a 2Kbytes of ROM for the program memory. The password is stored in the EPROM so that we can change it at any ...
ABSTRACT Cloning of Computer System is very essential in a computing area. This project focuses more on how computer system could be coupled and maintained effectively and efficiently without any fault during assembling of the system. Throughout this project we shall focus on each and every components needed for assembling and also there functions. The main reason why people go for assembling of system instead of buying a new system is to allow them to have good and satisfactory q...

ABSTRACTVoting is a very important process in the Nigerian political system. It is one of the means and most effective method of ensuring a legitimate government through popular participation. To enthrone sound democracy and stability in the political system in Nigeria, a system of rig-free voting has to be put in place. Online voter registration systems supplement the traditional paper-based process, by which new voters fill out a paper form that is submitted to election officials, who c...
ABSTRACTThe project “microcontroller based intelligent traffic light system with automatic street light and warning light” was designed to tackle the traffic issues in the country so as to establish automatic traffic control and monitoring system with near perfection. The project intelligent traffic light with automatic street light and warning light is a complex microcontroller based project that was designed to control traffic on a four way road network.The system is embedded with sens...
ABSTRACT In a developing economy like Nigeria financial resources are scarce commodity. Hence, cheaper means of accomplishing tasks even within the presence of scarce resources are always explored. This paper presents the design and implementation of a software intercom on local area network (LAN). The design provides a solution that eliminates the use of expensive hard-wired intercoms and Private Automatic Branch Exchange (PABX) by making use of only LAN and full multimedia computer allowing...
