IR Sender Arduino

Question

I want so controll my TV with my arduino. I know that the HEX code for the power button:0xFD020707. I got a IR sender module: S: Digital3, -:GND, +:5v This is my code i tryed:

It is not doing anything on the TV and connected a reciver but its just telling 0x0(when hitting a button on the remote it tells the HEX code)

The TV to turn on or the reciver to see the signal

``
    #include <IRremote.h>

    IRsend irsender;

    void setup() {
      Serial.begin(9600);
      pinMode(12, OUTPUT);
    }

    void loop() {
      delay(2000);
      digitalWrite(12, HIGH);
      //Power//
      irsender.IRsendNEC(0xFD020707, 32); //Power Code
      Serial.println("Power");
      delay(2000);
      digitalWrite(12, LOW);
    }

Answer 1

You are missing the call to irsender.begin in setup. Look at the example codes from the IR library that you are using and see how they call it.
