Controlling a ( or some) device(s) via IR

[Corvl]

Hello all,

Having been a happy vera3 and a bridged lite owner I was still missing some options. I am so happy this arduino stuff came available. I recently build an actuator to controll my floorheating.

The second device I would like to make is a device which at least switch off my mediabox via IR. It would be nice if it is possible to also controll some functions on my television ( Samsung) as well , like switching on.

For this project I have ordered a Arduino nano and this IR shield http://www.ebay.de/itm/400602576265?_trksid=p2060778.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

And offcourse a 2,4 Transceiver Module.

Next week when I am home I will put this together on an Arduino UNO for testing.
When it is working , it will be nice to also include a temp sensor on it , a humidity sensor, I read somewhere , someone is working on a air-quality sensor.

But first the IR-bit.

This is the sketch from the "build" area of this website:

---

   // Example sketch showing how to control ir devices
  // An IR LED must be connected to Arduino PWM pin 3.
   // An optional ir receiver can be connected to PWM pin 8. 
   // All receied ir signals will be sent to gateway device stored in VAR_1.
   // When binary light on is clicked - sketch will send volume up ir command
   // When binary light off is clicked - sketch will send volume down ir command
   
   #include <MySensor.h>
   #include <SPI.h>
   #include <IRLib.h>
   
   int RECV_PIN = 8;
   
   #define CHILD_1  3  // childId
   
   IRsend irsend;
   IRrecv irrecv(RECV_PIN);
   IRdecode decoder;
   //decode_results results;
   unsigned int Buffer[RAWBUF];
   MySensor gw;
   MyMessage msg(CHILD_1, V_VAR1);
   
   void setup()  
   {  
           irrecv.enableIRIn(); // Start the ir receiver
     decoder.UseExtnBuf(Buffer);
     gw.begin(incomingMessage);
   
     // Send the sketch version information to the gateway and Controller
     gw.sendSketchInfo("IR Sensor", "1.0");
   
     // Register a sensors to gw. Use binary light for test purposes.
     gw.present(CHILD_1, S_LIGHT);
   }
   
   
   void loop() 
   {
     gw.process();
     if (irrecv.GetResults(&decoder)) {
       irrecv.resume(); 
       decoder.decode();
       decoder.DumpResults();
           
       char buffer[10];
       sprintf(buffer, "%08lx", decoder.value);
       // Send ir result to gw
       gw.send(msg.set(buffer));
     }
   }



   void incomingMessage(const MyMessage &message) {
     // We only expect one type of message from controller. But we better check anyway.
     if (message.type==V_LIGHT) {
        int incomingRelayStatus = message.getInt();
        if (incomingRelayStatus == 1) {
         irsend.send(NEC, 0x1EE17887, 32); // Vol up yamaha ysp-900
        } else {
         irsend.send(NEC, 0x1EE1F807, 32); // Vol down yamaha ysp-900
        }
        // Start receiving ir again...
       irrecv.enableIRIn(); 
     }
   }
       
   // Dumps out the decode_results structure.
   // Call this after IRrecv::decode()
   // void * to work around compiler issue
   //void dump(void *v) {
   //  decode_results *results = (decode_results *)v
   /*void dump(decode_results *results) {
     int count = results->rawlen;
     if (results->decode_type == UNKNOWN) {
       Serial.print("Unknown encoding: ");
     } 
     else if (results->decode_type == NEC) {
       Serial.print("Decoded NEC: ");
     } 
     else if (results->decode_type == SONY) {
       Serial.print("Decoded SONY: ");
     } 
     else if (results->decode_type == RC5) {
       Serial.print("Decoded RC5: ");
     } 
     else if (results->decode_type == RC6) {
       Serial.print("Decoded RC6: ");
     }
     else if (results->decode_type == PANASONIC) {	
       Serial.print("Decoded PANASONIC - Address: ");
       Serial.print(results->panasonicAddress,HEX);
Serial.print(" Value: ");
     }
            else if (results->decode_type == JVC) {
        Serial.print("Decoded JVC: ");
     }
     Serial.print(results->value, HEX);
     Serial.print(" (");
     Serial.print(results->bits, DEC);
     Serial.println(" bits)");
     Serial.print("Raw (");
     Serial.print(count, DEC);
     Serial.print("): ");
   
     for (int i = 0; i < count; i++) {
       if ((i % 2) == 1) {
         Serial.print(results->rawbuf[i]*USECPERTICK, DEC);
       } 
       else {
  Serial.print(-(int)results->rawbuf[i]*USECPERTICK, DEC);
}
Serial.print(" ");
     }
     Serial.println("");
   }
   */

But how does it work??

If I understand correctly , when I point my ( original) IR-transmitter of the mediabox to the IR reciever ( which is connected to pin 8 , the signal will be stored somewhere on VAR_1 , I expect I can see this somewhere on the GUI of my vera3

This IR-code has to be copy-paste in the sketch.
Here:

---

 if (incomingRelayStatus == 1) {
  irsend.send(NEC, *0x1EE17887, 32*); // standby
 } else {
  irsend.send(NEC, *0x1EE1F807, 32*); // switch on

---

How am I doing so far??
