Hi :). I'm trying to use infaredLED to send out data and listen to infaredReceiver that recieve data back to my Arduino but doesn't work program not go to work in ir.recv command . Here is serial port output with sourcecode below(sry for my bad english 
)
send
send
send
send
send
#include <IRremote.h>
int RECV_PIN = 2;
IRrecv irrecv(RECV_PIN);
IRsend irsend;
decode_results results;
char character ;
void setup()
{
Serial.begin(9600);
irrecv.enableIRIn();
}
void loop() {
for (int i = 0; i < 3; i++) {
irsend.sendSony(0xa90, 12); // Sony TV power code
Serial.println("send");
delay(1000);
}
//*/
if (irrecv.decode(&results))
{
Serial.print("recv signal ... ");
switch (results.value)
{
case NULL : /* irsend.sendSony(0xA91, 12);*/
character = 0xA91 ;
Serial1.println("character");
break;
case 0xB90:
Serial1.println("character");
break;
case 0xC90:
Serial1.println("character");
break;
case 0xB91: /*irsend.sendSony(0xA92, 12);*/
character = 0xA92 ;
Serial1.println("character");
break;
case 0xC91: /*irsend.sendSony(0xA92, 12);*/
character = 0xA92 ;
Serial1.println("character");
break;
case 0xB92: /*irsend.sendSony(0xA93, 12); */
character = 0xA93 ;
Serial1.println("character");
break;
case 0xC92: /*irsend.sendSony(0xA93, 12); */
character = 0xA93 ;
Serial1.println("character");
break;
default:
character = 0xA93;
Serial.println("cannot specified data signal @_@");
break;
}
delay(100);
irrecv.resume(); // Receive the next value
}
}
