arduino The advantage of is that the library files of each module are relatively complete

Can find the corresponding library function, here we need rfid Library function

The code is as follows

       
       #include <SPI.h>
       
#include <RFID.h>
       
#include <Servo.h>
       
Servo myservo;
       
extern uint8_t SmallFont[];
       
RFID     rfid(10,8);    //D10-- Connect SDA、D8-- Pick up RST  D13-- Connect SCK D11-- Connect MOSI D12-- Connect MISO RQ Don't pick up 
       
unsigned char serNum[5];
       
void setup()
       
{
       
  Serial.begin(9600);// The serial port is used to read the card number to be added , Then write it into the program manually 
       
   pinMode(7,OUTPUT);
       
  myservo.attach(9);// Steering gear pin position 9
       
  myservo.write(3); // Actuator initialization 0 degree 
       
  SPI.begin();
       
  rfid.init();
       
}
       
void loop()
       
{
       
  long randNumber = random(0, 20);
       
  unsigned char i,tmp;
       
  unsigned char status;
       
  unsigned char str[MAX_LEN];
       
  unsigned char RC_size;
       
  // Find card 
       
  rfid.isCard();
       
  // Card reading number 
       
  if (rfid.readCardSerial())
       
  {
       
    Serial.print("your card id is   : ");
       
    Serial.print(rfid.serNum[0]);
       
    Serial.print(" , ");
       
    Serial.print(rfid.serNum[1]);
       
    Serial.print(" , ");
       
    Serial.print(rfid.serNum[2]);
       
    Serial.print(" , ");
       
    Serial.print(rfid.serNum[2]);
       
    Serial.print(" , ");
       
    Serial.print(rfid.serNum[4]);
       
    Serial.println(" ");
       
// The following is the card number change area 
       
    if(rfid.serNum[0]==001||rfid.serNum[0]==002){// The first screening
