AUTOMATIC NIGHT LAMP WITH MORNING ALARM USING MICROPROCESSOR
AUTOMATIC NIGHT LAMP.pdf (Size: 228.48 KB / Downloads: 327)
INTRODUCTION
This Project "Automatic Night Lamp with Morning
Alarm" was developed using Microprocessor. It 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.
OBJECTIVE
1)To learn and develop knowledge in designing
the application by using the microprocessor.
2)To learn how to write an assembly language
and combining with the hardware.
3)To learn how make a full report of
project Microprocessor
