Final year projects Engineering/ Diploma/ BCA/ MCA Contact 9448847874 Vensoft Technologies is a Electronic Design Services (EDS) for VLSI / EMBEDDED and MATLAB, delivering a wide variety of end- to -end services, including design, development, & testing for customers around the world. With proven expertise across multiple domains such as Consumer Electronics Market, Infotainment, Office Automation, Mobility and Equipment Controls. Vensoft Technologies is managed by Engineers / Professionals possessing significant industrial experience across various application domains and engineering horizontals.Our engineers have expertise across a wide range of technologies, to the engineering efforts of our clients. Leveraging standards based components and investments in dedicated test lab infrastructure, we offer innovative, flexible and cost-effective services and solutions. “We are sure you don’t want to say “This is what I said but not the one I want” when we deliver. So before we start any custom application development project, we always ask our client to define scope of the project. Without having defined scope, you will not be able to measure whether we have satisfied your requirements. It does not mean that it is your duty to give us defined scope. We are here to help you with that. Our experts will be in touch with you during this phase and prepare requirement spects and get it signed from you once you are happy with the same.” Contact Us Mob: 9448847874 Mangalore 4th Floor Vasudev Towers Hotel Satkar Building Near Bus stand BC Road-574219 http://vensofttechnologies.wordpress.com/ http://www.ieeedeveloperslabs.in/ Email: vensoftprojects@yahoo.com Mobile number: 9448847874 8051 PIC16 ARM7 renesas gsm gps zigbee ethernet touchpanel thermal printer webcam image processing communication based m.tech projects

Examination room guide using RFID for the jumbling
system based Exams
ABSTRACT:
The main objective of this project is to develop an embedded system, which is
used to verify and authenticate the authorized and display the room number.
Radio-frequency identification (RFID) is a technology that uses radio waves to
transfer data from an electronic tag, called RFID tag or label, attached to an object,
through a reader for the purpose of identifying and tracking the object. Some RFID tags
can be read from several meters away and beyond the line of sight of the reader. The
application of bulk reading enables an almost-parallel reading of tags.
The tag's information is stored electronically. The RFID tag includes a small RF
transmitter and receiver. An RFID reader transmits an encoded radio signal to interrogate
the tag. The tag receives the message and responds with its identification information.
Many RFID tags do not use a battery. Instead, the tag uses the radio energy transmitted
by the reader as its energy source. The RFID system design includes a method of
discriminating several tags that might be within the range of the RFID reader.
Whenever the student enters into the Examination center, he has to keep his
RFID TAG to the reader which is attached to our microcontroller based embedded board.
And enters the password (if necessary, their roll number is password) through the keypad
interfaced. At that moment the reader will checks weather the information of the student
is correct or not and then it will decide to display the student room number on LCD
display. If the information of the student is correct then he will be permitted inside
otherwise he will not permit inside and switches on the buzzer. The information of the
student will be send to the microcontroller through one wire protocol. And the
information of the access system will be displayed on the LCD which we embedded to
our board.
This project uses regulated 5v, 750ma power supply. 7805 three terminal voltage
regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify
the ac output of secondary of 230/18v step down transformer.
