    • VCC (Power)
    • GND (Ground)
    • SCK (Serial Clock)
    • MOSI (Master Out Slave In)
    • MISO (Master In Slave Out)
    • SS (Slave Select)

• Antenna:

• • Integrated antenna for RF communication, designed for optimal range and reliability.

• LED Indicator:

• • An onboard LED indicator can be used to signal the status of the reader (e.g., power on, card detected).

Wiring Connections:

1. Power Connection:

1. • Connect the VCC pin to the power supply (3.3V-5V).
   • Connect the GND pin to the ground.

2. SPI Connections:

1. • Connect the SCK, MOSI, MISO, and SS pins to the corresponding SPI pins on your microcontroller.

3. Optional LED Connection:

1. • Connect the LED to a digital pin for status indication, if desired.

How to Use:

1. Install Required Libraries:

1. • Install necessary libraries (e.g., MFRC522 library for Arduino) through the Arduino IDE Library Manager or download them from GitHub.

2. Connect the Module:

1. • Wire the RC522 module to the microcontroller according to the wiring connections mentioned above.

3. Upload Example Code:

1. • Load example code provided by the library to test the setup. Modify the code as needed to suit your application.

4. Power Up:

1. • Turn on the power supply to the microcontroller and the RC522 module.

5. Scan RFID Cards:
