This research will also add to the current body of literature on this subject and will also act as a resource for academics, researchers, and students interested in conducting future research on this or a similar topic.

The light sensitive alarm is an electronic circuit that detects a sudden shadow falling on the light sensor and sounds the bleeper. When this happens, the circuit will respond to gradual charges in brightness to avoid false alarm. The beeper sounds for only a short time to prevent the battery from running flat. Normal light can be use. The circuit will work best if a beam of light is made to fall on the light sensor. Breaking this beam will then cause the bleeper to sound. The light sensor is a ... read more

Transformer is one of the indispensable devices mostly in Electric Power Transmission, Transformer Step-down or Step-up, the output voltage/current to the design requirement. This project was meant to show the necessary step and methods of designing and constructing a typical step-up auto transformer with tapping. In this project, we gathered information from both primary data (personal interview) and secondary data (information from textbook and internet). The project work consist of copp... read more

The project, electronics display board system began as commercial electronic publishing (electronic display) which started in the mid-1970s with the development of databases of scientific, legal, and business information. These were used mainly by information specialists in large companies and universities, and ran on mainframe computers or minicomputers. Few small businesses or people at home used form of electronic publication, since the information itself was too specialized, and the softw... read more

The need for a remote control alert system that can control domestic appliances and various lighting points and sockets has often been a concern for users. At times users find it inconvenient and time consuming to go around turning their appliances on or off each time there is power outage or each time they are leaving the house for work. It has also often led to damage of appliances due to the fact that an appliance was not turned off before leaving the house.Domestic Appliances, The Objecti... read more

The purpose of this project is to produce a narrative description of the design and construction of a microcontroller based dot matrix advert display. Firstly computer aided design is the modeling of physical system on Computers allowing both interactive and automatic analysis of design variant and the expression of design in a form suitable for manufacturing. This follows by explaining the microcontroller based dot matrix advert display as a device which is fast gaining wide acceptance and appl... read more

The industrial batch counter is an electronic and electrical device that handles the counting and controls the flow of individuals using an automated slide door that allows access only when the administrator permits. The technique involved in the design is a simple sensor unit that opens and closes the door when someone obstructs the light path. These parameters can be used to determine when someone has moved in or out of the conference hall (for instance). The light sensing type involves monito... read more
