i want to get two decode values from two sensors at the same time
any one know how to do it with this code

#include <IRremote.h>

int RECV_PIN = 11;

IRrecv irrecv(RECV_PIN);

decode_results results;

void setup()
{
Serial.begin(9600);
irrecv.enableIRIn(); // Start the receiver
}

void loop() {
if (irrecv.decode(&results)) {
Serial.println(results.value, HEX);
irrecv.resume(); // Receive the next value
}
delay(100);
}

Use two Arduinos.

At the same time?
The IR signals will interfere with each other.

:confused:
no any method??

nope
it will give decode results

Well then, since you are sure that it can be done (it can't), go right ahead.

The IR library uses a timer to decode the incoming data. A timer means ONE timer. The same timer every time. Two instances of the class will use the SAME timer and the instances WILL interfere.
