This project is based on GSM MODEM & PIC16F877Aµcontroller.
For doing this project we use some of the software like
 Embedded C for programming the application software to the microcontroller.
 Protel schematic software is used for designing the circuit diagram for this project.
 Express PCB software is used for designing the PCB for this project.
(Since PCB making is a big process and involves lot of machineries which are expensive, we are going to outsource this to the manufacturer.
Now a days every one need automation for their devices, so that these can be contr..................[:=> Show Contents <=:]

Real- Time Systems:
One subclass of embedded systems is worthy of an introduced at this point. As commonly defined, a real-time system is a computer system that has timing constraints. In other words, a real-time system is partly specified in terms of its ability to make certain calculations or decisions in a timely manner. These impo..................[:=> Show Contents <=:]

a resistance of 2.2 kilo-ohms in daylight, which drops below 50 ohms when light beam falls on it. (An LDR of nearly 2cm diameter has been used in this circuit.) Comparator LM311 (IC1) compares the level set at pin 3 (nearly 6V, set using a 47k pot) with the level at pin 2. When light is falling on LDR1, its voltage is above 1V and IC5 has a low output at its pin 1. When no light is falling on LDR1, its voltage drops below 1V and IC1 output at its pin 1 becomes high.
The output from the Op-amp is given as the clock for seven segment counter 4033.The counter count 1 for each high going pulse...................[:=> Show Contents <=:]
