An Arduino Nano controls two relays which in turn can turn the car on, start it, and turn it off. Instead of adding a button for “push to start” he opted for a 13.56MHz RFID module.

RFID enables wireless data collection by readers from electronic tags attached to or embedded in objects, for identification and other purposes. This article describes the construction of a simple ...

Spread the loveArduino RFID projects have become increasingly popular in recent years due to the simplified technological mechanisms provided by the Arduino platform. The integration of RFID ...

An Arduino, a spent roll of toilet paper, magnet wire, and a few passive components are what’s needed to build this RFID spoofer. It’s quick, dirty, and best of all, simple. However, [S… ...

How Arduino RFID Systems Work Arduino RFID technology works by using electromagnetic waves in the radio frequency spectrum for wireless communication and data transfer between RFID tags and readers.

This can be mitigated somewhat by explicitly slowing down the speed of the SPI interface in the Arduino code, by including #define MFRC522_SPICLOCK (400000u) (Sets SPI bus to 400kHz) prior to ...

• RFID Keyfob Detection: Detects RFID keyfobs using the Arduino and announces the detected person’s name. • Accessibility Focus: Designed for individuals with visual impairments or other disabilities ...

Learn to build an RFID based attendance system using Arduino with step-by-step instructions, circuit diagrams, and complete code. This $35 DIY project replaces expensive commercial systems with ...

I just received my RC522 RFID reader and made this simple Arduino access control system that uses the reader, a buzzer for the alarm and a relay shield for the security system. The relay can be used ...

In this proposed project, the quantity of liquid dispensed depends on the delay time for each digital output pin of the Arduino, which gets added through Arduino programming. Here we have used five ...
