Description
INTRODUCTION
Emergency light is an integral part of household electronics nowadays. We all Emergency light is used during the power failure to light up the home. As it is used during the power failure, it should last long, hence generally bright white LEDs are used in emergency light, because they produce more light and consume less power. Emergency light is very useful and popular project in DIY section. So today we are going to build a simple and cost effective emergency light.
In this emergency light circuit, when the Power goes OFF, the emergency light activates automatically. We have used four bright white LEDs; more LEDs can be added to produce more light considering that total current consumption should not exceed the supply current. Ultra bright white LED consumes 3v and 20mA current.

Job application portal system project report
The human resource departments in many Institutions have various processes which include checking employee attendance, disbursing payrolls, applying for jobs, handling company events and training programs, handling leave and absence requests and lastly, checking on employee welfare. These processes, however, are handled manually for example job application could become tedious due to the many processes that an applicant would have to undergo at the physical establishment in order to apply for a job of choice. Such manual handling of these processes was tiring and therefore cause inaccuracy and inefficiency.
The developed solution was a web-based information system that would seek to automate these processes in the human resource department. It would be able to make job application easier for applicants and ensure that employees requesting leaves and absences would be able to do so by communicating to the right channels through the system.
The system was developed using the prototyping methodology. Other tools that were used include PHP as the programming language, Brackets as the IDE , MySQL as the DBMS and usability testing as the testing method.

Online assignment management system project report
Almost all collages and higher institutions of learning, includes some form of assignment in their assessment for each courses. The assignments are allocated manually by the instructor to the students, which are either carried out in groups or by individual student. This manual management of assignment is becoming obsolete due to its inconvenience, inefficiency, and low accuracy. Currently, web-based management systems have been widely implemented due to the development of Web technologies. Therefore in other to effectively manage these assignment process, a well-designed assignment submission system is needed, hence the need for an online assignment submission system to facilitate the allocation, collection and marking of the assignments scripts.
This project introduces a web-based Assignment Management System, which automates all the manual aspects of the conventional way of handling assignment. Its friendly user interfaces allow instructors and students to handle their assignments in a convenient, efficient, and simplified manner. In addition, this system also has very good features of portability and extensibility. The aim of this study was to create a web based online assignment submission system and the objective of the system is to facilitate easy interaction of Instructors and students for assignment allocation, submission and grading purposes. The system was created to eliminate the traditional process of allocating an assignment and collecting the feedback for the assignment. The system was implemented as a web based application through the useful tools of hypertext mark-up language, cascading style sheet and Java Script as the front end design while using MySQL database for storing and retrieving data as the back end tool. The implementation of this system was aimed at downloading and uploading online assignments for students, with each interface having information about the instructions and its description for easy access. The main goal of this project is to design and implement online assignment submission and provide an interface use for uploading and downloading assignment by instructors and the submission by the students, while the instructor also perform the task of grading each student submission automatically. The most obvious advantage offered by this online assignment submission system is that it offers an easy and faster transmission of assignments between both the instructor and the students than using the manual process.
