 The aim of this SMART CARD READER AND WRITER WITH ATTENDANCE ACCESS project is to maintain the attendance of employee/student in computer. Nowadays so many companies and schools are maintaining their employee/students attendance in note only. It damage by insects or water or fire. Anybody can change their details easily. To avoid these disadvantages we developed this project. In this project the smart card contains the student/employee details. Whenever the person enter to the campus they have to insert the card into the card reader, that time the person details will stored in computer with current time.  

WORKING PRINCIPLE. 

This project is used to maintain the employee/student attendance. The student/employee details are stored in smart card. VB application software we can add/remove the person details. Before entering the room that person should insert the card in to the reader. Now the microcontroller will read the details of persons from card through reader slot. After reading the details the microcontroller sends these details to the VB application through serial port. The VB application software will receive the details from microcontroller and it will check with its database. If permission is available the software will store the person ID, date and time in its own database.

Smart card based automated parking system embedded system project explains about new technique for solving parking problems and provide easy method of parking. In present scenario people are not interested to take their cars to public places like shopping malls, gardens because time taken for parking procedure is late. This project will consider present parking system issues and develop advanced parking system.  In this new method users are provided with smart card while entering in to parking gate, and users will use this card for check in and check out of there vehicle. This application is integrated with messaging feature where users will receive message about parking space availability. This card can be used only for one time for next time he/she need to buy another card and this card can be used until amount in the card is completed. 

WORKING PRINCIPLE:  By paying the amount a smart card is given to the owner of the vehicle & the amount is stored in the database using VB software. If the person wants to park his/her two or four wheeler he/she has to insert the Smart card in the card reader slot, the microcontroller is programmed in such a way that when the card is detected  microcontroller will start the I2C communication to communicate with the smart card. The micro controller reads the amount from card & sends the data to the controller through serial port. The controller checks with the database for balance amount & for authorization if the card is valid and the amount present is sufficient, and then sends the permission to the micro controller to open the gate. If not permitted it will display “ACCESS DENIED” with buzzer sound.

 The main aim of this RFID ACCESS CONTROL SYSTEM  AND  SECURITY  WEBCAM WITH  VOICE  ACKNOWLEDGEMENT project is power security for companies or Lab. In this project we are using RFID.           In order to organize or control different access systems by person or items, this application should provide accurate security. So RFID is used to provide security by embedding access control in ID cards. These cards are used monitoring attendance and also prevent authorizing access.

Working: 

            Controller will check whether the tag identification number provided by the RFID reader have the access permission or not. If have, access permission will be provided to that particular person, i.e. door control signal enabled.  Otherwise an alert message will be sent to a predetermined mobile number and alarm will be activated. Each person’s entry timing and access permissions can be seen on the LCD.  EEPROM (AT24c04) is used to keep the employ database. Relay circuit regulates communication to controller by GSM module and computer. Computer is used to modify database and to list entry details. MAX 232 and ULN 2803 are used as line drivers.

 In many Organizations we will be having many devices which are located in remote places. If we want to control those devices, every time we should go to that place and make certain operations to control that device and get the job done.  For example if we want to print a document, for this work we want a printer in our place. If that Printer is placed far away from us, we have to goto that place and get our work done. But this consumes time. To overcome this problem we have developed a software that saves time and we can control remote devices through LAN. The main seek of this REMOTE CONTROL USING LAN NETWORK project is to develop a controlling system which will controls embedded devices through LAN network. Visual Basics is used to develop the front end. IN front end we can control many devices as well as we can add devices whichever we want to control through LAN.

WORKING PRINCIPLE:    

                                              This system uses Visual Basics software, which is deigned as the application platform monitors and co-ordinates with the embedded devices, attached to the LAN network. Using this project we can communicate with any embedded systems or machine connected to the LAN network. This project is mainly doing an application with the embedded LAN card available. This card mainly has a interface to the LAN network and it has a serial port .The micro controller with different devices will be connected according to the application. The remote through LAN means 4 or 5 relays will be connected and when from a PC if we want to control any of the relays or switch OFF or switch ON the relays we have to send a command telling switch off relay one with the IP address of that network etc .we can also do process control of machine the same way like always update the machine details like temperature, speed of the machine motor, or the productions of the machine etc.in this project we have totally 2 relays to switch on and off any device and also an input device to show the rpm of the motor and also update the computers which require this data.so on the computer screen we can see and also monitor the rpm of for example the fan motor rpm and also see the screen updated every second.

Introduction:                                  Remote controlling Home Using Zigbee embedded system project is used in  various home applications, such as home appliance controlling, security systems and automation etc are not very easy to do it manually with human interaction.             

            The fact is it is not possible to access these areas directly because of the some physical and technological problems. So it is better to employ some automated devices to monitor and control these devices or security systems.       

                  If it is a large housing colony, there will be a lot of   devices and security systems to monitor and control. Connecting different monitoring and control equipments in different houses are not possible. All the houses should be monitored and controlled with one master system and this is a best approach also. Inter connecting all houses with wires are also not practical. It should be wireless. A better way is a wireless network that can communicate in between houses and the main server. Here comes the importance of wireless home automation and monitoring system network based on Zig Bee.

 Abstract:                                  

  In this home automation and monitoring system, all the houses are fixed with sensors to capture different parameters and also with security systems. As the houses will be in different places we should do a wireless network to communicate with all the sensors fixed in different homes. For this wireless communication we use Zigbee protocol and technology to obtain a best result.     

        We use single board computers to collect sensor information and send to the master equipment. In order to maintain various parameters like pressure, vibration and temperature master equipment server is used.  Control different parameters will be done through communication between control equipment and control devices.                         For the prototype we will interface temperature sensors and vibration sensors and these data will be sending over radio (zigbee) to the server and monitor these parameters and relays to control different devices.

In the proposed Embedded system Project On Intelligent traffic control system , the traffic signal lights are controlled by single board computers with the reference of vehicle density on the road. If the vehicle density is high then the interval of green signal will be faster than the default time interval. The four side single board computers will check the density and that information will send to the server that controls the traffic signals. So four side single board computers will be connected in a wireless network. The wireless network obtained with Zigbee wireless protocol  With this technique the passengers can save time at the traffic signals. 

Working principle

                              Normally the traffic signals will ON and OFF in an equal interval of time. But when the vehicle density increases on the road the interval of green signal and red will change. On the road there will be fixed with IR transceiver module and  it will be placed some distance apart from the  traffic junction. So when ever the vehicle density increases, some vehicles may stopped on the IR transceivers fixed on the road. The IR will detect the vehicle and check for certain time interval , if the vehicle is still on the same place after a certain time then the system will take it as vehicle density. According to the time intyerval of reflection of IR , the system will calculate the percentage of vehicle density and that information will be sending to the server over radio communication.

The server will collect all information from all the side single board computers and calculate which side road should show green signal and how much time green signal should be there.
