An Arduino Uno RFID access-control prototype that unlocks an electronic latch when a registered card is scanned. The firmware reads card UIDs through an MFRC522 RFID module, displays access status on ...

First we have to set up a master tag, then the system goes into normal mode. If we scan an unknown tag, access will be denied, but if we scan the master, we will go into program mode from where we can ...

Connect the components as per the wiring diagram. Ensure the RFID module is properly connected to the Arduino's SPI pins. Connect the I2C LCD display to the Arduino's I2C pins (SDA and SCL). Upload ...

For starters, you need a pre-wired NFC RFID module as the key hardware. NFC and RFID projects have become a huge trend, but many modules are pricey for electronics hobbyists and need a complex setup.

Transform your door security with an Arduino-based RFID lock system for seamless, keyless entry and enhanced protection. If you want to know detailedly, how to make RFID Door lock using Arduino, check ...

The use of Radio Frequency IDentification (RFID) technologies is growing. Many different applications are implemented in various sectors, and used for very different purposes. RFID enables wireless ...

Recently, I’ve been trying to build an RFID-based interactive musical instrument using Arduino—by swiping different RFID tags to trigger corresponding musical notes. It’s not only suitable for kids to ...

[Pierre] recently bought his first car and decided to make his own RFID electric starter for it! An Arduino Nano controls two relays which in turn can turn the car on, start it, and turn it off.

[Jason] really wanted to build an RFID controlled garage door opener and decided to turn to Arduino to get the job done. For someone who’s never worked with an Arduino before, he really seemed to know ...
