Notice Board Abstract— This is the model for displaying notices in colleges on electronic notice board by sending messages in form of SMS through mobile; it is a wireless transmission system which has very less errors and maintenance. The hardware board contains microcontroller AT89c52 at the heart of the system. The microcontroller is interfaced with GSM Modem via MAX232 level convertor. It is used to convert RS232 voltage levels to TTL voltage levels and vice versa. The hardware also has a 64K

node. Thus the stranger is identified at the main node. A series of interface, signal processing, and communication systems have been implemented in micro power CMOS circuits. A micro power spectrum analyzer has been developed to enable low power operation of the entire WINS system. Thus WINS require a Microwatt of power. But it is very cheaper when compared to other security systems such as RADAR under use. It is even used for short distance communication less than 1 Km. It produces a less amount

ABSTRACT : Railways are the popular mode of Transport in almost all major cities of the World. Railways are the most widely used and comfortable modes of transportation system. The major cause for railway accidents is collision of trains on the same track. The main aim of this anti collision system is to identify collision points and to report these error cases to main control room nearer to the station as well as grid control station. Majority of accidents occurred due to improper communication

fed to on-board devices and integrated circuits. 2. INTRODUCTION TO EMBEDDED SYSTEMS What is Embedded system? An Embedded System is a combination of computer hardware and software, and perhaps additional mechanical or other parts, designed to perform a specific function. An embedded system is a microcontroller-based, software driven, reliable, real-time control system, autonomous, or human or network interactive, operating on diverse physical variables and in diverse

ports, and timers. Unlike a general purpose computer, which also includes all of these components, a micro controller is designed for a very specific task - to control a particular system. Micro controllers are sometimes called embedded microcontrollers, which just means that they are part of an embedded system. A microprocessor is a general-purpose digital computer with central processing unit (CPU), which contains arithmetic and logic unit (ALU), a program counter (PC), a stack pointer (SP)

Dhamdhere, rnd7528@g.rit.edu I. Introduction The Internet of Things (IoT) helps us sense meaningful data from the physical world. In recent years, its ability to sense the data has increased tremendously, which increases

internals ought to get in touch with us to talk about their necessities; this arrangement of modules is equipped more towards giving the preparation to drawing nearer those spaces as opposed to as top to bottom preparing on a particular methodology. Embedded C contains key data for anybody creating inserted frameworks, for example, microcontrollers, continuous control frameworks, cell phone, PDAs and comparable applications. This C course depends on numerous years of experience showing C, broad modern

recreational sport called Geocaching as part of my unit of study Embedded system design during my final semester. I worked on this project along with my team mates with whom I shared common interests in the field of my desire. I was guided by my lecturer Dr. Jason White during the whole period of this particular development. b) BACKGROUND [CE 1.2] GPS enabled mobile device I chose embedded system design unit due to my inordinate interest in embedded microcontroller programming. It was one of the requirements

Statement of Purpose The first decade of 21st century will be remembered for the incredible advancement in the electronics. A decade ago there were televisions which occupied a large table whereas the present day flat screen LCD or LED televisions can be hung to a wall. The desktops are replaced by laptops and which in turn are replaced most recently by the tablets. This reduction in the size of electronic gadgets with increase in working efficiency over the years amazed me. Hence naturally, I
