HOME AUTOMATION AND SECURITY SYSTEM VIA PSTN
The objective here is to develop a home automation and security system which can be controlled and monitored remotely using any telephone line. The user can enter into the system by entering the valid pin cod e. After entering into the system, the user can control the status of devices connected with the system using any Public Switched Telephone Network (PSTN). The system can also be implemented for security purposes in banks or at home. If the user is at outstation, he can change the status of the lights remotely for security reasons. The heart of the system is a PIC micro-controller (PIC18F4520) which controls the complete working of the system. The GSM modem is also interfaced with the micro-controller. The remote user can also monitor the current status of the devices by sending SMS message to the GSM modem. The system can be controlled and monitored from anywhere by using telephone line.

An embedded system is a computer system designed for specific control functions within a larger system, often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts. By contrast, a general -purpose computer, such as a personal computer (PC), is designed to be flexible and to meet a wid e range of enduser needs. Embedded systems control many devices in common use today Embedded systems contain processing cores that are typically either microcontrollers or digital signal processors. The key characteristic, however, is being dedicated to h andle a particular task. Since the embedded system is dedicated to specific tasks, design engineers can optimize it to reduce the size and cost of the product and increase the reliability and performance. Embedded systems are designed to do some specific t ask, rather than be a general-purpose computer for multiple tasks. Some also have real -time performance constraints that must be met, for reasons such as safety and usability Embedded systems are not always standalone devices. Many embedded systems consist of small, computerized parts within a larger device that serves a more general purpose. The program instructions written for embedded systems are referred to as firmware, and are stored in read-only memory or Flash memory chips. They run with limited comp uter hardware resources: little memory, small or non-existent keyboard or screen.

PERIPHERALS
Embedded Systems talk with the outside world via peripherals, such as:
Serial Communication Interfaces (SCI): RS-232, RS-422, RS-485 etc. Synchronous Serial Communication Interface: I2C, SPI, SSC and ESSI (Enhanced Synchronous Serial Interface) Universal Serial Bus (USB) Multi Media Cards (SD Cards, Compact Flash etc.) Networks: Ethernet, LonWorks, etc. Fieldbuses: CAN-Bus, LIN-Bus, PROFIBUS, etc. Timers: PLL(s), Capture/Compare and Time Processing Units Discrete IO: aka General Purpose Input/Output (GPIO) Analog to Digital/Digital to Analog (ADC/DAC) Debugging: JTAG, ISP, ICSP, BDM Port, BITP, and DP9 ports.

MICROCONTROLLERS

Embedded Systems Projects, IEEE 2012 Abstracts
A microcontroller (sometimes abbrev iated µC, uC or MCU) is a small computer on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals. Program memory in the form of NOR flash or OTP ROM is also often included on chip, as well as a typically small amount of RAM. Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose applications. Microcontrollers are used in automatically controlled products and devices , such as automobile engine control systems, implantable medical devices, remote controls, office machines, appliances, power tools, toys and other embedded systems. By reducing the size and cost compared to a design that uses a separate microprocessor, memory, and input/output devices, microcontrollers make it economical to digitally control even more devices and processes

ATMEL 89C51 MICROCONTROLLERS
The Atmel AT89 series is an Intel-8051-compatible family of 8 bit microcontrollers (µCs) manufactured by the Atmel Corporation. Based on the Intel 8051 core, the AT89 series remains very popular as general purpose microcontrollers, due to their industry standard instruction set, and low unit cost. This allows a great amount of legacy code to be reused withou t modification in new applications The AT89C51 is a low-power, high-performance CMOS 8-bit microcomputer with 4Kbytes of Flash programmable and erasable read only memory (PEROM). The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the industrystandard MCS-51 instruction set and pin out. The on-chip Flash allows the program memory to be reprogrammed in -system or by a conventional nonvolatile memory programmer. By combining a versatile 8 -bit CPU with Flash on a monolithic chip, the Atmel AT89C51 is a powerful microcomputer, which provides a highly flexible and cost-effective applications solution to many embedded control
