In this tutorial, we are dealing with yet another interfacing technique. This time we are interfacing an RFID Reader which can read RFID Tags to Arduino. RFID is Radio Frequency Identification. An RFID reader is used to read RFID tags (which contain certain unique data stored in a chip). A...
The RC 522 usage is simple and complex at the same time. Even its library has too much complexity to understand. First, understand that library examples and documentation are all for SPI but the same library is useable for other UART and I2C Serial communication. Arduino Interfacing Example To...
