this works perfectly! Thanks for all the advice!

int value = 0;

{

pinMode(ledPin2, OUTPUT);
pinMode(ledPin3, OUTPUT);
pinMode(ledPin4, OUTPUT);

}

void getAdistance(){
pinMode(pin, OUTPUT);
delay(500);
digitalWrite(pin, LOW);
delayMicroseconds(5);
digitalWrite(pin, HIGH);
delayMicroseconds(5);
digitalWrite(pin, LOW);
pinMode(pin, INPUT);
duration = pulseIn(pin, HIGH);
}

void fadeIn(int outPin)
{
for(int value = 4; value <= 250; value++)

}
}
