The term RFID stands for Radio Frequency Identification that makes use of non-contact radio frequency electromagnetic fields to transfer data. RFID technology is similar to barcode technology, but uses radio waves to capture data from tags.Tags are of two types: passive reader active tag and active reader passive tags. RFID tags can be detected as long as they are within the range of RFID reader. Some tags require battery, but most of the tags run without a battery and they work on the principle of electromagnetic induction.
Nowadays security is the major concern for all as the incidences of theft have become routine, and are on the rise especially in houses, banks, ATM’s, jewelry shops, etc. To ensure security in all these places and others, different systems can be implemented by using various technologies like GSM, Bluetooth, RF, RFID, etc. This article briefs about some security systems that use Arduino and also some Arduino based projects.

Technologies are growing enormously fast and their usage is becoming common in our day-to-day life as many of us are now started doing activities like shopping and paying online. This project is based on RFID technology that delivers couriers at the destination address and simultaneously updates the location of the parcel in the internet. [Read more…]
In this era of revolutionary technology, enormous projects have been implemented especially for patients and disabled persons. Communication plays a key role in all of these projects and the projects that use several communications like Zigbee, Ethernet, GPRS, etc.
Nowadays microcontroller projects have become very popular and widely implemented as academic projects by most of the students. These projects are low-cost projects that provide a good practical knowledge to the students. Keeping their cost-effectiveness in view, the projects given in this article are based on data transfer between two or more microcontrollers that use wireless communications like IR and Zigbee communications.
