Arduino is an open-source electronics platform based on easy-touse
hardware and software. It's intended for anyone making
Arduino is a tool for making computers that can sense and control
more of the physical world than your desktop computer. It's an
open-source physical computing platform based on a simple
microcontroller board, and a development environment for writing
software for the board.
Arduino can be used to develop interactive objects, taking inputs
from a variety of switches or sensors, and controlling a variety of
lights, motors, and other physical outputs. Arduino projects can be
stand-alone, or they can be communicate with software running on
your computer (e.g. Flash, Processing, MaxMSP.) The boards can
be assembled by hand or purchased preassembled; the open-source
IDE can be downloaded for free.
The Arduino programming language is an implementation of
Wiring, a similar physical computing platform, which is based on
the Processing multimedia programming environment.
What is RFID?
A basic RFID system consists of three components:
a) An antenna or coil
b) A transceiver (with decoder)
c) A transponder (RF tag)
Electronically programmed with unique information. There are
many different types of RFID systems out in the market. They are
categorized according to their frequency ranges. Some of the most
commonly used RFID kits are as follows:
1) Low-frequency (30 KHz to 500 KHz)
2) Mid-Frequency (900KHz to 1500MHz)
3) High Frequency (2.4GHz to 2.5GHz)
These frequency ranges mostly tell the RF ranges of the tags from
low frequency tag ranging from 3m to 5m, mid-frequency ranging
from 5m to 17m and high frequency ranging from 5ft to 90ft. The
cost of the system is based according to their ranges with lowfrequency
system ranging from a few hundred dollars to a highfrequency
system ranging somewhere near 5000 dollars.
