After uploading this to the arduino, you should open the serial monitor (Tools), and press any button in the remote, (this should give you something like this "FD08F7"). After doing this with every button, we can get to the next part.

1#include <IRremote.h>
2
3const int RECV_PIN = 7;
4IRrecv irrecv(RECV_PIN);
5decode_results  results;
6
7void setup(){
8  Serial.begin(9600);
9  irrecv.enableIRIn();
10}
11
12void  loop(){
13  if (irrecv.decode(&results)){
14        Serial.println(results.value,  HEX);
15        irrecv.resume();
16  }
17}
18

#include <IRremote.h>

const int RECV_PIN = 7;
IRrecv irrecv(RECV_PIN);
decode_results  results;

void setup(){
  Serial.begin(9600);
  irrecv.enableIRIn();
}

void  loop(){
  if (irrecv.decode(&results)){
        Serial.println(results.value,  HEX);
        irrecv.resume();
  }
}

Here, You will be able to replace my remote values with yours to make it easier to see wich button you are pressing, and more organized for future projects. Note: Before adding your HEX code, you will have to add a "0x" just as it is done in row 20, 23, etc After doing this and uploading this code, instead of getting HEX values in your serial monitor, you should get what button you pressed

Even though the IR reciever in the diagram is not the one I'm using, it's the only one I found in Fritzing, i'm using a VS1838
