of power cut action. 2)In order to remove this drawback though auto-starter facility is available‚ it is necessary to go near to the switching station to turn off the switch. Now a days timer circuits are available‚ but in most of the cases the operation time of the load is not fixed. So due to use of timer circuit there may be unloaded operation of device if operation of the device is finished before predetermined time. 3)If switching station is far away from the user‚ then these problems becomes

Multiuser SMS Based Wireless Electronic 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

WIRELESS ELECTRONIC NOTICE BOARD WITH MULTI NODES USING ZIGBEE COMMUNICATION SYSTEM CHAPTER-1 1.1 INTRODUCTION: Notice boards play a vital role mostly in educational institutions. The events‚ occasions or any news‚ which has to be passed to the students‚ will be written on the notice boards present in every floor in the colleges or schools. The present system is like‚ a person will be told the news and he has to update this news on all the notice boards

Chapter-01 Introduction Implementation of an Map Following Vehicle (MFV) is a step towards making a ground vehicle that can work at its own‚ which can make decisions and do the tasks which we require from it to be done. It would be a vehicle which can process the data in real time and take the respective decisions on the bases of that processed data. The project is based on integration of different hardware and software modules and their interaction to produce an efficient outcome. 1

A signal or function generator is used to produce periodic signals of the frequency‚ amplitude‚ and waveform needed for input to the device under test. The counter/timer can measure time intervals and frequencies very accurately‚ and the digital multimeter measure voltages‚ currents‚ resistance‚ and it can test silicon diodes and transistors. Everything you do in an electronics laboratory depends upon your familiarity
