This is a simple setup with an Adrduino Uno, 125kHz RFID reader and interface board, relay toggle, 16x2 LCD display, and 125kHz RFID cards. When you scan the card, if authorized, it toggles the relay.

The code is pretty simple. The RFID reader will check for any tags in the vicinity and if a tag is found, the reader will read the Unique ID from the tag. And if the UID matches with the UID in the ...

I just received my RC522 RFID reader and made this simple Arduino access control system that uses the reader ... On the next lines you need to change the cards codes with the ones you have. You’ll ...

Lastly, connect the antenna to ANT1 and ANT2 pin in any polarity. The code for RFID card reader using Arduino Nano and RDM6300 is very simple. Here we used the rdm6300 library to read the data. The ...

This article describes the construction of a simple Arduino RFID Access control DIY (Do It Yourself) Project using Arduino UNO and a RFID reader module (EM-18) to control an LED and a Relay. Circuit ...

It is very easy to create a nice looking RFID ... with an Arduino MKR of your choice and our ArduiTouch MKR kit with 2.4 inch display only. You can use this reader for door access or intruder alarm ...

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 ...

3. Fig. 2: Code to obtain RFID card ID number Fig. 3: EM-18 and Arduino programming circuit Put the RFID tag in front of the RFID reader module and see its 12-digit decoded value. The decoded values ...

This is called backscattering. The backscatter is detected and interpreted by the RFID reader, which then sends the data to a computer or a microcontroller such as the one with Arduino. Just as a ...

[Pierre] recently bought his first car and decided to make his own RFID electric starter for it! An Arduino Nano controls ... one of our readers took it a step further a few years ago, and starts ...

Patrick explains more about his latest hardware creation and its features : Meet the Arduino Compatible RFID ... code, so that you can modify it as you see fit! How it Works: It is very simple.
