In this Raspberry Pi RFID RC522 tutorial, I will be walking you through the steps on how to setup and wire the RFID RC522 chip with your Raspberry Pi.
The VCC and GND pins of the module are connected to the 3.3V and GND pins of Arduino respectively. The Reset pin is connected to the D9 and SS, MOSI, MISO, and SCK pins are connected to the D10, D11, D12, and D13 pins of the Arduino respectively. The SS and RST pins are co...
The RFID reader signals are everywhere with it’s promity to detect a tag. When a RFID tag comes in the proxmity of the RFID reader the tag detects the readers signal through a coil present in it which converts the received RF signal into a electrical signal. This converted signal alone...
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...
‘0’ which is sent from the smartphone when the ‘LED: OFF’ button is pressed, we will turn the LED off and send back to the smartphone the String “LED: OFF”. On the other hand, if we receive the character ‘1’ we will turn the LED on and send back the ...
