IR REmote Code Review

Projects Programming

hello I've wrote this code parts of it I've copied and pasted from online sources.
My problem is that when i press the button that ring the buzzer it will ring then it will not accept pressing any more buttons on the IR remote unless i restart the device any suggestions what could be the reason?

#include <IRremote.h>
#include <Servo.h>
const byte IR_RECEIVE_PIN = 2;

#define LED1 8
#define LED2 9
#define LED3 3
#define LED4 13
Servo myservo;
int pos = 0;
int buzzer = 7;
void setup()
{
   Serial.begin(9600);
   Serial.println("IR Receive test");
   IrReceiver.begin(IR_RECEIVE_PIN, ENABLE_LED_FEEDBACK);
   myservo.attach(5);
   pinMode(LED1, OUTPUT);
   pinMode(LED2, OUTPUT);
   pinMode(LED3, OUTPUT);
   pinMode(LED4, OUTPUT);
}

void loop()
{
   if (IrReceiver.decode())
   {
      String ir_code = String(IrReceiver.decodedIRData.command, HEX);
      Serial.println(ir_code);

      if(ir_code == "16")
        {digitalWrite(LED1, HIGH);}
      else if(ir_code == "19")
        {digitalWrite(LED1, LOW);}
      if(ir_code == "c")
        {digitalWrite(LED2, HIGH);}
      else if(ir_code == "18")
        {digitalWrite(LED2, LOW);}
      if(ir_code == "8")
        {digitalWrite(LED3, HIGH);}
      else if(ir_code == "1c")
        {digitalWrite(LED3, LOW);}
      if(ir_code == "42")
        {digitalWrite(LED4, HIGH);}
      else if(ir_code == "52")
        {digitalWrite(LED4, LOW);}
       if (ir_code == "5e")  // change according to your IR remote button number
        {
         for (pos = 0; pos <= 180; pos += 5) { // goes from 0 degrees to 180 degrees
        // in steps of 1 degree
        myservo.write(pos);              // tell servo to go to position in variable 'pos'
        delay(15);                       // waits 15ms for the servo to reach the position
      }
        }
      else if  (ir_code == "5a")  // change according  to your IR remote button number
        {
          for (pos = 180; pos >= 0; pos -= 5) { // goes from 180 degrees to 0 degrees
        myservo.write(pos);              // tell servo to go to position in variable 'pos'
        delay(15);                       // waits 15ms for the servo to reach the position
      }
        }
       if (ir_code == "4a"){
        int i=0;
        do {
          i++;
          tone (buzzer, 450);
          delay (200);
          noTone (buzzer);
          delay (200);
          }while(i<3);}
      else if(ir_code =="52"){
         int i=0;
            do {
              i++;
              tone (buzzer, 450);
              delay (200);
              noTone (buzzer);
              delay (200);
              }while(i<5);}
                IrReceiver.resume();
   }}

These two libraries both use Timer1 hardware and don't work properly together. There is a third-party "ServoTimer2" library that uses Timer2 instead and will work with IRremote.h

thanks I couldn't find the ServoTimer2 in library manager. can you suggest another library and how to get those library commands?

a good opportunity to use @StefanL38 new tutorial:

Use IrReceiver.start() instead of IrReceiver.resume()!
