Simple RFID code for Arduino This is a simple setup with an Adrduino Uno, 125kHz RFID reader and interface board, relay toggle, 16x2 LCD display, and 125kHz RFID cards.

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.

Arduino/ESP32 code for R200 long-range UHF RFID reader The R200 is a UHF RFID module based on the EPC Gen-2 (ISO18000-6C) protocol. What does that mean in practice? Well, it can read up to 60 tags per ...

Fig. 1: Circuit diagram of the RFID Based access control system An RFID system typically consists of three key elements: 1. An RFID tag, or transponder, that carries object-identifying data (unique ID ...

We designed the RFID based authentication system using Arduino that include the transceiver, antenna, and decoder.

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… ...

A cool RFID music table has been created using Arduino, iPod, and RFID tags to make it easy to change albums by simply changing the RFID tag. Each RFID tag has an individual code number relating ...

The purpose of the project is to spoof a simple low frequency 125kHz RFID tag with the use of an Arduino and only a few components. A single Arduino pin provides the control once tag is assembled and ...
