ABSTRACT This project work is on the construction of dark activated street lighting system. Which aimed at activating a switch or AC street light at sunset and deactivate it at sunrise. This Dark activated street light can trigger a relay to operate an AC street light at Sunset. The lamp remains on till morning and then turns off. This eliminates the need of switching the Porch lamp daily and also helps to light the road/street. The […]
ABSTRACT The main objective of this project was to ensure a proper security to building against theft or intruder. This device functions as a major security alarms used in residential, commercial, industrial, and military properties for protection against burglary (theft) or property damage, as well as personal protection against intruders . It is an electronic device that is connected to the battery being installed in and gets activ […]
ABSTRACT The aim of this work is to design and fabricate an astable multivibrator. An Astable Multivibrator is an oscillator circuit that continuously produces rectangular wave without the aid of external triggering. Astable Multivibrator is also known as Free Running Multivibrator. The astable multivibrator is not stable and it repeatedly switches from one state to the other. Astable Multivibrator using transistor is very simple, eas […]
ABSTRACT This work is on auto night lamp using high power LED. An Automatic Night Lamp Using High Power LEDs is a circuit which turns ON the LED lights interfaced to it at night time and it turns OFF the lights automatically when it is day. This project discuses the working of turning on or off of high power LEDs with light intensity. The element which is used for sensing light in the circuit is the light dependent resistor. The resi […]
ABSTRACT This work is a transistorized electronic ignition system. An electrical system for use with an ignition system of the type including an ignition coil and breaker points. The electrical system provides for low current through the breaker points to minimize wear and corrosion of the breaker points, provides a high primary winding current at saturation of the primary winding and of the transistors of the electrical system to pro […]
ABSTRACT This work is transistor tester. This transistor tester circuit uses 555 timer IC for testing both PNP and NPN transistors. This circuit is simple as compared to other transistor testers, and therefore, is useful for technicians as well as students. The circuit is developed using basic electronic components like resistors, diodes, LEDs and NE5555 are used. By using this circuit, different faults can be checked –like to know wh […]
ABSTRACT Radio receiver design includes the electronic design of different components of a radio receiver which processes the radio frequency signal from an antenna in order to produce usable information such as audio. This project only concentrates on fm receiver design. The complexity of a modern receiver and the possible range of circuitry and methods employed are more generally covered in electronics and communications engineering […]
