Dieser LED pulsiert logarithmisch und oszilliert an Hand des Potentiometers schneller oder langsamer:

#define sensor_in 0
int potiValue = 0;
float tmp;
int led_pin = 5;

void setup(){
  Serial.begin(9600);
  pinMode(led_pin, OUTPUT);

}
void loop(){
  potiValue = analogRead(sensor_in);
  Serial.println();
  tmp = map(potiValue,0,1023,1,20);

  for (float i = 1; i<=255; i = i=i*1.4){
    analogWrite(led_pin, i);
     delay(tmp);
  }
  for (float i = 254; i>=2; i = i=i/1.4){
    analogWrite(led_pin, i);
    delay(tmp);
  }
}
