This Arduino UNO project uses an RFID reader, a servo motor, a buzzer, an LCD display, and a 3x4 keypad to create a lock and key system that is able to store a password and two slots for ...

An automatic toll gate system using Arduino revolutionises traditional toll collection by eliminating manual intervention.

Arduino library for MFRC522 and other RFID RC522 based modules. Read and write different types of Radio-Frequency IDentification (RFID) cards on your Arduino using a RC522 based reader connected via ...

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 ...

[Matt] has mixed up a batch of two RFID reading door lock systems. While the “door lock” part of the setup has yet to come into existence, the “RFID reading” section is up and running. By using the ...

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 ...

What is the Arduino IDE? As we know we need a text/code editor to write the code, a compiler to convert that code to machine code or binary files so that the microcontroller can understand, and also ...
