LCD BASED SECURITY SYSTEM


Security is one of the most important concerns for everybody. Everybody wants to secure their home, offices, industry from unauthorized persons. To make this task an easy, this is one of the cheap and best system.

This project consists of LCD which shows that whether the person entered is authorized or not. The user, who wants to enter into the room or office, has to enter a pin or password through keypad and if the entered password is correct the door will open. The verification of password is done by using mi ....etc

A Brief Description:
This project is written in C language. Its a simple project with efficient hacking prevention from Brute Force etc. The basic user lock is of 5 Digits and Master Lock is of 10 digits so its not easy for an intruder to break the lock unless you keep the code simple.The input is taken from a 4x3 Keypad (please see the schematic for more information) and Display the user input on a 2x16 LCD. A pin is assigned as output for activating and deactivating the lock. For demonstration i have connected an LED to that pin.

MOVING MESSAGE ON LCD


The main objective of the project is to interface an LCD with microcontroller and display the moving message on to the LCD. The software used to program is keil compiler.

Very good advertising results are obtained from these unique displays with latest technology. You can change the message as often as you want with ordinary computer keyboard without any prior experience of any kind LCDs available in various sizes and are also made to custom requirements.

Moving message on LCD are ideal for all type of commerci ....etc

Abstract— Computational Private Information Retrieval (cPIR) protocols allow a client to retrieve one bit from a database, without the server inferring any information about the queried bit. These protocols are too costly in practice because they invoke complex arithmetic operations for every bit of the database. In this paper, we present pCloud, a distributed system that constitutes the first attempt toward practical cPIR. Our approach assumes a disk-based architecture that retrieves one page with a single query. Using a striping technique, ....etc

i wanted the detailed circuit diagram for heart rate monitor using microcontroller,the output of which would be displayed digitally on LCD.it would be better if the pulses are taken using electrodes and not using finger probe as i am not that confident with the signal processing part.moreover i wanted to add temperature monitoring feature along with the above.is it possible using same microcontroller. ....etc
