IR reciever to LED (Update according to rules)

I'm trying to use an IR receiver to turn on the LED when I press power and turn off when I press power again, but I realized that might be too difficult so I settled for pressing 1 to turn on and 2 to turn off. I used an elagoo tutorial to make the IR receiver code and it works. Here is my code:

#include "IRremote.h"
int receiver = 11; // Signal Pin of IR receiver to Arduino Digital Pin 11
/*-----( Declare objects )-----*/
IRrecv irrecv(receiver);     // create instance of 'irrecv'
decode_results results;      // create instance of 'decode_results'

int incomingByte = 0;

/*-----( Function )-----*/
void translateIR() // takes action based on IR code received

// describing Remote IR codes 

{





switch(results.value)

{
case 0xFFA25D: Serial.println("POWER"); break;
case 0xFFE21D: Serial.println("FUNC/STOP"); break;
case 0xFF629D: Serial.println("VOL+"); break;
case 0xFF22DD: Serial.println("FAST BACK");    break;
case 0xFF02FD: Serial.println("PAUSE");    break;
case 0xFFC23D: Serial.println("FAST FORWARD");   break;
case 0xFFE01F: Serial.println("DOWN");    break;
case 0xFFA857: Serial.println("VOL-");    break;
case 0xFF906F: Serial.println("UP");    break;
case 0xFF9867: Serial.println("EQ");    break;
case 0xFFB04F: Serial.println("ST/REPT");    break;
case 0xFF6897: Serial.println("0");    break;
case 0xFF30CF: Serial.println("1");    break;
case 0xFF18E7: Serial.println("2");    break;
case 0xFF7A85: Serial.println("3");    break;
case 0xFF10EF: Serial.println("4");    break;
case 0xFF38C7: Serial.println("5");    break;
case 0xFF5AA5: Serial.println("6");    break;
case 0xFF42BD: Serial.println("7");    break;
case 0xFF4AB5: Serial.println("8");    break;
case 0xFF52AD: Serial.println("9");    break;
case 0xFFFFFFFF: Serial.println(" REPEAT");break;  

default: 
 Serial.println(" other button   ");

}// End Case

delay(500); // Do not get immediate repeat


} //END translateIR
void setup ()   /*----( SETUP: RUNS ONCE )----*/
{
[color=red]int incomingByte = 0;
pinMode (13, OUTPUT);  [/color]
Serial.begin(9600);
Serial.println("IR Receiver Button Decode"); 
irrecv.enableIRIn(); // Start the receiver

}/*--(end setup )---*/


void loop()   /*----( LOOP: RUNS CONSTANTLY )----*/
{  // send data only when you receive data:
[color=red]if (Serial.available() > 0) {
  incomingByte = Serial.read();
  if (incomingByte = "1") 
  {pinMode, HIGH;}
  if (incomingByte = "2"){ pinMode, LOW;}[/color]
}

if (irrecv.decode(&results)) // have we received an IR signal?

{
 translateIR(); 
 irrecv.resume(); // receive the next value
}}

 
/* --(end main loop )-- */
