Automatic Night Lamp with Morning Alarm using 8085 Microprocessor

Image
As the name suggests “Automatic Night Lamp with Morning Alarm” was developed using Microprocessor. 8085 is the Heart of the system. The sensors are made with help of LDR which are Light Dependent Resistors, whose Resistance is inversely proportional to the Light falling on it. The LDR converts the light energy into electrical energy and this variable electrical energy was converted into digital signal (0 or 1) by using the timer IC555. The Timer IC output goes low when light falls on the LDR and the timer IC output goes high when the LDR was placed in dark circuit is as shown in below figure: circuit the flow chart for Automatic Night Lamp with Morning Alarm using 8085 Microprocessor is as shown in following fig. flow chart the program for Automatic Night Lamp with Morning Alarm using 8085 Microprocessor this is as shown below make sure that the Power supply pins & Port number before you connect the Hardware to the Trainer Kit. 0001   0000 0002   0000

Basic Principle Of Alternator

Image
A.C. generators or alternators (as they are usually called) operate on the same fundamental principles of electromagnetic induction as d.c. generators. They also consist of an armature winding and a magnetic field. But there is one important difference between the two. Whereas in d.c. generators, the armature rotates and the field system is stationary, the arrangement in alternators is just the reverse of it. In their case, standard construction consists of armature winding mounted on a stationary element called stator and field windings on a rotating element called rotor. The details of construction are shown in Fig. alternator The stator consists of a cast-iron frame, which supports the armature core, having slots on its inner periphery for housing the armature conductors. The rotor is like a flywheel having alternate N and S poles fixed to its outer rim. The magnetic poles are excited (or magnetised) from direct current supplied by a d.c. source at 125 to 600 volts.
