Sadi rfid project HUE – leave and plate project

http://uk.youtube.com/watch?v=CdQ7zI_EphI&feature=related

I think this video is the most interesting video of FRID that I have come across because they have presented in a good layout, one can’t see the mess of wires and other stuff they might have used. As the video is in Chinese I didn’t understand a word but what I did guess from watching it is that, the leaves in water create different noises. The leaves must have a chip inside them and once they are in water they chip triggers off and makes the already saved tunes on the chip.

Though this is a casual video but seems like a radio tuner to me. The lady uses her RFID card to activate some kind of recording.

The project that I like from that video is when you touch your Oyster card to the RFID card Reader it takes your picture and Displays it on the second screen. I think the designers are using RFID as a switch which activates when the card is scanned and takes a quick snap and delivers it to the second screen.

The video contains details of what RFID card is, how it’s used and where it can be used.

My Rough Idea for Final Project

My influence is from the Book:

Making Things Talk

ISBN-13: 978-0-596-51051-0

Project Title: Reading Tags in Processing

Page number 308-315

The project is based on FRID reader, where once the RFID chip is scanned through the reader, it activates the lights of the room and once the reader cannot read the tag it turns the lights off.

The project is in quite detail.

I am planning to design a RFID card reader which would display the results on a screen.

What is RFID?

RFID stands for Radio-Frequency Identification.

RFID is a scanning antenna with a transceiver and a transponder.

The short form refers to small electronic devices that consist of a small chip and an antenna. The chip on average is capable of carrying 2,000 bytes of data or less.

The RFID device has the same purpose as a magnetic strip on the back of a credit card or ATM card or a bar code; it provides a unique identifier for that object/person. And, just as a bar code or magnetic strip must be scanned to get the information, the RFID device must be scanned to recover the identifying information.

The common problem with RFID is that the reader collision occurs when the signals from two or more readers overlap.

RFID technology has been available for more than fifty years, but is in use more today than it was five decades ago.

Some differences between RFID and Barcode are:
· RFID are more expensive than barcodes.
· RFID tags have read/write capability (Oyster Card), whereas information cannot be added on barcodes.
· RFID tags can be read at much greater distance than barcodes.
· RFID tags work faster than Barcodes.

Thinking about the technology being secure would be the next question and the answer to that is No. The invasion to an RFID only requires an appropriately equipped scanner.
I guess this is where chip and pin comes in. The only way to keep the chip and data safe is to add a pin/ password to it.

RFIDs have many uses, such as animal/human tracking, credit-cards, keeping track of heavy duty containers and many more.

RFID inside a living body (animal/human).

People have been implanting RFIDs inside them for various reasons. The chips are cased in such a way that they don’t react or irritate but moves around under the skin. The size of the RFID chip which is inserted into the body is usually the size and diameter of a grain of rice, which is inserted with a hyperdermic-type needle.

Seven Segment Display

http://www.electrofriends.com/articles/8051_programs/seven_seg/7_seg_pin_config.gif

Sketch 1

Black box is the touch sensitive case.

Every time the button is pressed, message appears. This will require no sensors (less coding).

I can use the switch code for the button on the box and link the screen with the button.

Mini Project based on Arduino

For the mini project I will be making a touch sensitive box which will display a message or a word once touched. For this project I’ll be using a seven segment display screen and a motion sensor. The sensor will be attached to the box so every time one picks up the box a message will appear.

The box will hide all the wiring, no USB connection will be visible, and as this is the requirement of the exercise. The idea is to engage the user with the design.

For wireless technology such as Bluetooth, Infrared there is another type of Arduino but I’ll be using the old technology of Arduino as I don’t require my Arduino to be wireless.

Purpose of the project is to get back into the Arduino and try new codes for ourselves. Try the sensors and come up with something small but realist.

The only interactivity in the mini project will be to pick the box to see what comes up on the display screen.

What is Arduino?

According to www.arduino.cc/ Arduino is an open- source electronics prototyping platform based on flexible, easy-to-use hardware and software. Arduino is a simple physical computing platform based on input/output board.Arduino can be connected to software’s like Macromedia flash, Pure Data, Processing, Supercollider on your computer. The programming language used for Arduino is C/C++.Arduino software is an integrated development environment cross platform Java application which acts as a code editor and is also able of transferring firmware successively to the board.
