I found this video. I used the same sketch and hit the reset just as in the video but nothing's happening. I'm done. I apologize for wasting your time.

#include <IRremote.h>

IRsend irsend;

void setup()

}

void loop() {
	for (int i = 0; i < 3; i++) {

		delay(40);
	}
	delay(5000); //5 second delay between each signal burst
}
