The wastage of electrical power cannot be over-emphasized in FCT College of Education, Zuba-Abuja as many lighting bulbs, street-lights, electrical fans are always ON even when not in use. The college community is characterized by electrical power wastage. However, the motivation for this research was to curtail the electrical power wastage and reduce the high cost of electricity. This research was designed to control ON and OFF time of any electrical appliance connected to its output and could as well be used as a digital clock. The objective of this research was to control the ON and OFF time of air conditioning. The design included a microcontroller (ATMEGA328) that was programmed to achieve the timing operation. The Light Emitting Diode (LED) displayed the ton (Time ON) and the t0ff (Time OFF); four keys set the hour and the minutes; and the relay was activated whenever the time set elapsed, causing the air conditioning to be energized/dis-energized automatically. A time of 3:19 was set to test the ON switching. An air conditioning connected to the developed system was activated at exactly 3:19. Also, a time of 5:57 was set to de-activate the already ON electric bulb. The electric bulb was switched OFF at exactly 5:57. The developed switching system was tested and satisfactorily switched ON and OFF air conditioning as desired and pre-set by the user.

The issue of Crimes been committed in our society these days has become an issue that every government and the society in general has to be concerned with. Stolen of vehicle has increased tremendously and sometimes such vehicle are used in committing criminal activities such as armed robbery, kidnapping and of recent insurgency as it is been witness in some part of Nigeria. In view of these challenges, adequate provision or records of stolen, identified and recovered vehicle are not readily available and as such very important. The development of vehicle movement notification and location is one of the solutions to vehicles owner in order to ensure speedy notification, identification and recovery of their vehicles and as well reduce criminal activities in the society. The system uses a developed application installed in a mobile phone device which will be embedded in a vehicle to notify the owner when the vehicle is driven by unauthorized user. A GSM mobile phone was used to communicate with the vehicle owner whereby the user sends SMS to communicate with the mobile phone sensor installed in the vehicle. A web application was also developed to determine the real-time vehicle location and as well as record of database information system of found or missing vehicles. The system was test run and the results obtained shows how effectiveness is it in determining vehicle movement, location and notification as it is been driven within or outside its jurisdiction.
