infrared is picking up garbage and stopping code

so i have recently been using a infrared sensor to control a rgb’s colour.

#include <IRremote.h>
#include <IRremoteInt.h>

//Set initial mode (Colour Value Mode) to Colour Value 1

int redpin =9;
int bluepin =10;
int greenpin =11;
int RECV_PIN = 6;

IRrecv irrecv(RECV_PIN);
decode_results results;

void setup()
{
Serial.begin(9600);
irrecv.enableIRIn(); // Start the receiver

pinMode(RECV_PIN,INPUT);
pinMode(redpin, OUTPUT);
pinMode(bluepin, OUTPUT);
pinMode(greenpin, OUTPUT);

}

void loop()
{
unsigned long lastValue = results.value;

if (irrecv.decode(&results))
{
Serial.println(results.value, HEX); // Use HEX or DEC
irrecv.resume(); // Receive the next value
}
digitalWrite(redpin, HIGH);
digitalWrite(greenpin, HIGH);
digitalWrite(bluepin, HIGH);
switch (results.value) {
case 0xFFFFFFFF:
results.value = lastValue;
break;

case 0xFF30CF: // when button 1 is pressed only red will turn on
digitalWrite(redpin, LOW);
digitalWrite(greenpin, HIGH);
digitalWrite(bluepin, HIGH);
break;

case 0xFF18E7: // when button 2 is pressed only blue will turn on
digitalWrite(bluepin, LOW);
digitalWrite(greenpin, HIGH);
digitalWrite(redpin, HIGH);
break;

case 0xFF7A85: // when button 3 is pressed only green will turn on
digitalWrite(greenpin, LOW);
digitalWrite(redpin, HIGH);
digitalWrite(bluepin, HIGH);
break;

case 0xFF10EF: // when button 4 is pressed only leds red and blue will turn on
digitalWrite(redpin, LOW);
digitalWrite(bluepin, LOW);
digitalWrite(greenpin, HIGH);
break;

case 0xFF38C7: // when button 5 is press only leds blue and gree will turn on
digitalWrite(greenpin, LOW);
digitalWrite(bluepin, LOW);
digitalWrite(redpin, HIGH);
break;

case 0xFF5AA5: // when button 6 is press only leds green and red will turn on
digitalWrite(greenpin, LOW);
digitalWrite(redpin, LOW);
digitalWrite(bluepin, HIGH);
break;

case 0xFF42BD: // when button 7 is pressed all led colours will be on
digitalWrite(greenpin, LOW);
digitalWrite(redpin, LOW);
digitalWrite(bluepin, LOW);
break;

case 0xFF4AB5:
digitalWrite(redpin, HIGH);
digitalWrite(greenpin, LOW);
digitalWrite(bluepin, LOW);
delay (250);
digitalWrite(redpin, LOW);
digitalWrite(greenpin, HIGH);
digitalWrite(bluepin, LOW);
delay (250);
digitalWrite(redpin, LOW);
digitalWrite(greenpin, LOW);
digitalWrite(bluepin, HIGH);
delay (250);
digitalWrite(redpin, HIGH);
digitalWrite(greenpin, HIGH);
digitalWrite(bluepin, LOW);
delay (250);
digitalWrite(redpin, HIGH);
digitalWrite(greenpin, LOW);
digitalWrite(bluepin, LOW);
delay (250);
digitalWrite(redpin, LOW);
digitalWrite(greenpin, HIGH);
digitalWrite(bluepin, HIGH);
delay (250);
digitalWrite(redpin, LOW);
digitalWrite(greenpin, LOW);
digitalWrite(bluepin, LOW);
delay (250);
break;

case 0xFF6897: // ALL OFF (Stop button)
digitalWrite(greenpin, HIGH);
digitalWrite(redpin, HIGH);
digitalWrite(bluepin, HIGH);
break;

}

}

and just recently its becoming hard to control(wont respond or will just flicker the light and not hold its colour. and i saw im getting random hex values in the serial monitor, like (FF30CF
FFFFFFFF
FFFFFFFF
FFFFFFFF
FFFFFFFF
FFFFFFFF
CDE870EE
FF18E7
C60BDB3D
FFFFFFFF
FF30CF
FFFFFFFF
FFFFFFFF
FFFFFFFF
FFFFFFFF
FFFFFFFF
FF18E7
FFFFFFFF
FF7A85
FF10EF
FF38C7
49B0F626
the ffffffffff are normal but the ones like C60BDB3D are out of nowhere and i think are causing issues. im trying to drive 4 rgb leds off of it, if that helps

You have posted code without using code tags. The code tags make the code look

like this

when posting source code files. It makes it easier to read, and can be copied with a single mouse click. Also, if you don’t do it, some of the character sequences in the code can be misinterpred by the forum code as italics or funny emoticons. The “Code: [Select]” feature allows someone to select the entire sketch so it can be easily copied and pasted into the IDE for testing.
If you have already posted without using code tags, open your message and select “modify” from the pull down menu labelled, “More”, at the lower left corner of the message. Highlight your code by selecting it (it turns blue), and then click on the “</>” icon at the upper left hand corner. Click on the “Save” button. Code tags can also be inserted manually in the forum text using the code and /code metatags.

Unless the sketch is too large, it’s better if you post your code, rather than attach it. When it’s attached, we have to download it, create a folder then open your code in our IDE. And afterwards, the folder remains unless we navigate to the “Temp” folder and manually remove it. It’s much easier to just view the code in your post.
