IntroductionThis is the design and construction of a light sensitive circuit which when the sensor is blocked will activate the light emitting diode at the output. The output gain depends on the non-inverting input of the operational amplifier used in this demonstration. This system is made of different component which aided in the functionality of the design.Aim and ObjectiveIn this paper we are to design and construct a light sensitive circuit which senses an obstruction in the sensing unit...
ABSTRACTTransient over voltages have often been blamed for the malfunctioning of electrical power systems. This seminar paper is an overview which seeks to describe the state of the power system under transient condition. It also provides information on the rate of occurrence, on the wave shape, and on the energy associated with the transients, as a function of the location within the power system. Also, the basic principles of coordinated protection with specific experimental examples are eq...
ABSTRACTSecurity 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 t...
INTRODUCTION Digital systems design teams are facing exponentially growing complexities and need processes and tools that reduce the time needed to gain insight into difficult system integration problems. A digital system is a data technology that uses discrete (discontinuous) values. By contrast, non-digital (or analog) systems use a continuous range of values to represent information. Although digital representations are discrete, the information represented can be either discrete...
ABSTRACTCongestion remains a major challenge to telecommunications service provision both to the service providers as well as the subscribers. This seminar work attempted to determine the causes of congestion and evaluated congestion control mechanisms adopted by service providers in Nigeria using MTN Nigeria as a case study. Findings from the study showed that apart from the carrying capacity of the MTN network other factors such as the use of phones for data transfer and multimedia ac...
ABSTRACTThe project work titled Design and construction of a metal detector. When fully design and implemented would be able to detect any metallic material that is passing or coming close. This function would serve as a security check for dangerous metallic material as an alarm. Going by the sophisticated means of armed rubbers adopt these days in the breaking into bank supermarkets offices and highly secured area. No security system will be optimised or complete without the installation of ...

ABSTRACTThis project work is focused on the design and construction of obstacle detection system for the visually impaired. This paper reports on a study that helps visually-impaired people to walk more confidently. The study hypothesizes that a smart walking stick that alerts visually-impaired people over obstacles in front could help them in walking with less accident. The aim of the paper is to address the development work of a walking stick that could communi...
