/* 
 *  RFID Module RC522
 *  Simple Project:- Arduino will read RFID Tag and Display To the Serial Monitor!
 *  
 *  RFID RC522 and Arduino Uno Pin Configuration
 *  
 *  RFID RC522          Arduino Uno
 *  SS/SDA              D10
 *  SCK                 D13
 *  MOSI                D11
 *  MISO                D12
 *  IRQ                 Not Connected
 *  GND                 GND
 *  RST                 D9
 *  3.3V                3.3V
 *  
 *  //Note: We connected LCD to the Analog Pins.
 *  Remember, Analog Pins can be act as a Digital Pins,
 *  But Digital Pins CAN NOT be act as a Analog Pins.
 *  
 *  LCD(16x2) Connections
 *  
 *  VSS pin to GND
 *  VCC pin to 5V
 *  //We are connecting "Contrast pin to GND for Maximum Brightness"
 *  //You can also connect it to 10K Pot if you wish to change the Brightness Of LCD.
 *  VEE pin to GND 
 *  RS pin to Analog pin A0
 *  R/W pin to ground
 *  Enable pin to Analog pin A1
 *  D4 pin to Analog pin 5
 *  D5 pin to Analog pin 4
 *  D6 pin to Analog pin 3
 *  D7 pin to Analog pin 2
 *  LED+ pin to POWER
 *  LED- pin to GND 
 *   
 *  Servo is Connected to Digital Pin 5  
 *  
 *  RGB LED
 *  From RGB LED, We need Only Red and Green Color, 
 *  So we are not connecting Blue pin of the RGB. 
 *  
 *  Red pin to Digital pin 6
 *  Green pin to Digital pin 7
 *  
 *  Buzzer to Digital pin 8
 * 
 *  
 *  Note:- RFID uses SPI Protocol to transfer the information.
 *  I took the Melody(for the Buzzer) from, 
 *  File -> Examples -> Digital -> ToneMelody
