The Splendid Arduino and Parallax RFID Reader

Do you have any interest on the RFID stuff? If you did, then you must grab this chance, as you’re about to create an Arduino and Parallax RFID reader today!

By the way, do you know what the meaning of “RFID” is? Well, RFID is the short acronym for “Radio-frequency identification”, where it is an automatic identification method that relies on storing and remotely retrieving data, by using devices called “RFID” tags. Most of the time, the technology requires some extent of cooperation of an RFID reader and an RFID tag.

For your information, the RFID tag is basically an object and it can be applied into a product, animal, or person for the purpose of identification. Some of the tags can be easily read from several meters away!

The RFID tags mostly contain at least two different parts: An integrated circuit and an antenna. The integrated circuit is responsible for storing and processing information, while the antenna is for receiving and transmitting the signal.

The best part about this Arduino and parallax RFID reader is once it has fully connected and programmed, you can print the tag number in the serial monitor window.


If you refer to the above figure, you can see that the LED is red-in-color, this means that the module is in an active state and the antenna is transmitting. The LED will show green, if the module has been successfully powered-up!
