rf id help

please post your sketch so we can review your code, it looks like it may be in there

Thanks

hello, i have one more problem i have two programs that i want to combine one is : an rfid reader followed by a PIN (from a matrix keypad) another is GPS receiver. These two programs are working separately. this first program is:

#include <Keypad.h>

#include <SoftwareSerial.h>

SoftwareSerial RFID(12, 13);

String tag;

int LED=9;

void setup()

{

  //pinMode(8, OUTPUT);

  //pinMode(9, OUTPUT);

  //digitalWrite(8, LOW);

  //digitalWrite(9, HIGH);

  Serial.begin(9600);

  RFID.begin(9600);

   pinMode(LED,OUTPUT);

}

char c;

void loop(){

    while(RFID.available()>0){

    c=RFID.read();

    tag += c;

  }

tag=tag.substring(0,13);

while(tag.length()>0){

//Serial.print("ID: ");

Serial.println(tag);

tag="";

delay(200);

tag="";

}

delay(200);

tag="";

joseph_keypad();

}

void joseph_keypad()

{

  const byte ROWS = 4; // Four rows

const byte COLS = 4; // Four columns

// Define the Keymap

char keys[ROWS][COLS] = {

{'1','2','3','A'},

{'4','5','6','B'},

{'7','8','9','C'},

{'*','0','#','D'}

};

byte rowPins[ROWS] = { 5, 4, 3, 2 };

byte colPins[COLS] = { 8, 7, 6, A0 };

// Create the Keypad

Keypad keypad = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS );

  char key = keypad.getKey();

  if (key != NO_KEY){

    Serial.println(key);

     if(key =='#')

    {

      digitalWrite(LED,1);

    delay(500);

    digitalWrite(LED,0);

    delay(500);

    }

    else

    {

    digitalWrite(LED,1);

    delay(100);

    digitalWrite(LED,0);

    delay(100);

    }

  }

}

second program is :

#include <SoftwareSerial.h>

#include <TinyGPS.h>

#define RXPIN 10

#define TXPIN 11

#define TERMBAUD  9600

#define GPSBAUD  9600

TinyGPS gps;

SoftwareSerial uart_gps(RXPIN, TXPIN);

void getgps(TinyGPS &gps);

void setup()

{

  // Sets baud rate of your terminal program

  Serial.begin(TERMBAUD);

  // Sets baud rate of your GPS

  uart_gps.begin(GPSBAUD);

  Serial.println("");

  Serial.println("GPS Shield QuickStart Example Sketch v12");

  Serial.println("       ...waiting for lock...           ");

  Serial.println("");

}

void loop()

{

  while(uart_gps.available())     // While there is data on the RX pin...

  {

      int c = uart_gps.read();    // load the data into a variable...

      if(gps.encode(c))      // if there is a new valid sentence...

      {

        getgps(gps);         // then grab the data.

      }

  }

}

// The getgps function will get and print the values we want.

void getgps(TinyGPS &gps)

{

  float latitude, longitude;

  // Then call this function

  gps.f_get_position(&latitude, &longitude);

  Serial.print("Lat/Long: ");

  Serial.print(latitude,5);

  Serial.print(", ");

  Serial.println(longitude,5);

  int year;

  byte month, day, hour, minute, second, hundredths;

  gps.crack_datetime(&year,&month,&day,&hour,&minute,&second,&hundredths);

  // Print data and time

  Serial.print("Date: "); Serial.print(month, DEC); Serial.print("/");

  Serial.print(day, DEC); Serial.print("/"); Serial.print(year);

  Serial.print("  Time: "); Serial.print(hour, DEC); Serial.print(":");

  Serial.print(minute, DEC); Serial.print(":"); Serial.print(second, DEC);

  Serial.print("."); Serial.println(hundredths, DEC);

  //Since month, day, hour, minute, second, and hundr

  // Here you can print the altitude and course values directly since

  // there is only one value for the function

  Serial.print("Altitude (meters): "); Serial.println(gps.f_altitude()); 

  // Same goes for course

  Serial.print("Course (degrees): "); Serial.println(gps.f_course());

  // And same goes for speed

  Serial.print("Speed(kmph): "); Serial.println(gps.f_speed_kmph());

  //Serial.println();

  // Here you can print statistics on the sentences.

  unsigned long chars;

  unsigned short sentences, failed_checksum;

  gps.stats(&chars, &sentences, &failed_checksum);

  Serial.print("Satellites: ");

  Serial.println(gps.satellites());

}

please help me if possible..
