Send information from xbee end device to coordinator

[Diego Turcios]

Hi

I am working in a small project. Right now I can send information to my end device to turn on a lightbulb. 

I am building a web site for turning the light of my house. I want as feedback to know when the lightbulb is turn on. (Sometimes I will turn on the light manually, and I will like to know that)

What changes I have to make to my code in arduino?

This is my arduino code

/*

*rxOnOff

*Recieves packet from remote Coordinator

*Turns LED On or Off

*/

int LED = 11;                //Turn this LED on or off, depending on packet rx'd

int debugLED = 13;           //Flash light to indicate rx

int packet=-1;                 //Packet will be two bytes in length

int analogValue;

int PIN=12;

int RELAY=10;

void setup() {

  pinMode(LED, OUTPUT);

  pinMode(PIN, INPUT);

  pinMode(RELAY, INPUT);

  pinMode(debugLED, OUTPUT);

  Serial.begin(9600);

}

void loop() {

  

 if(Serial.available() >= 16){        //<--Changing the value from 21 to 16 fixed the problem! 

    

   if(Serial.read() == 0x7E){         //Look for starting byte

    

     digitalWrite(debugLED, HIGH);    //Flash Arduino LED (not the one on digital pin 11)

     delay(1000);                          //to indicate rx'ing data

     digitalWrite(debugLED, LOW);

     

     for(int i = 0; i <15; i++){      //Discard unused data (see XBee API protocol for more info)

       byte discard = Serial.read();

     }

     packet = Serial.read();          //This should be the first byte of "meat" data

   }

 }

if(digitalRead(PIN)==LOW){

 if(packet == 0x01){                  //If a '1' is pressed on keyboard side

   if(digitalRead(PIN)==LOW){

     digitalWrite(LED, HIGH);              //turn on red LED

     packet=-1;

   }

 }

}

if(digitalRead(PIN) == HIGH){  

  if(packet == 0x00){

    if(digitalRead(PIN)==HIGH)

    {

      digitalWrite(LED, LOW);

      packet=-1;

    }

  }

}

if(packet == 0x00){                  //If a '1' is pressed on keyboard side

   if(digitalRead(PIN)==LOW){

     digitalWrite(LED, HIGH);              //turn on red LED

     packet=-1;

   }

 }  

  

 if(packet == 0x01){

    if(digitalRead(PIN)==HIGH)

    {

      digitalWrite(LED, LOW);

      packet=-1;

    }

  }

   

}

Thanks

You can use the XBees I/O change detection feature to capture these sort of events. I do this with my garage door controller. You can find a description of the project and code here. http://rapplogic.blogspot.com/2011/10/xbeegoogle-talk-garage-door.html Disregard the google talk stuff
