got a problem with this while loop.
the first while loop prompts user for input and waits for that input, and put the input it in a variable, this one works fine, but then the next while loop should do the same, but it does not wait for input it just continues regardless if user enters something or not.
if you are quick enough and enters a second value, it will put that value into the variable.
Do i need to clear something first ??

Your code:-
Serial.println("indtast antal gange du ønsker den røde lysdiode skal blinke: "); //prompt bruger for input
while (Serial.available()==0){} //vent på input
redNumBlink=Serial.parseInt(); //put brugerindput i variabel
Serial.println("indtast antal gange du ønsker den grønne lysdiode skal blinke: ");//prompt bruger for input
while (Serial.available()==0){} //vent på input
greenNumBlink=Serial.parseInt(); // pit brugerinput i variabel
It looks like the serial buffer has something left in it after the parseInt() call. Try emptying it first like this:-
Serial.println("indtast antal gange du ønsker den røde lysdiode skal blinke: "); //prompt bruger for input
while (Serial.available()==0){} //vent på input
redNumBlink=Serial.parseInt(); //put brugerindput i variabel
while(Serial.available()!= 0){ // empty the buffer
Serial.read();
}
Serial.println("indtast antal gange du ønsker den grønne lysdiode skal blinke: ");//prompt bruger for input
while (Serial.available()==0){} //vent på input
greenNumBlink=Serial.parseInt(); // pit brugerinput i variabel
thansk mate it worked.
but should it not clear by it self?

Serial.parseInt() stops when a non digit character is read, such as linefeed or carriage return. What have you got the Line ending set to in the Serial monitor ?
linechange it would apear
juste changed it to no lineend, and remove the code, and that works to. but it was nice to know how to clear the buffer
