Arduino code k�rer langsomt

Hejsa alle.

Jeg sidder og roder lidt med at lave en lille styring i arduino med
4 tmp9700 temperatur sensorer som skal vise temperaturen diverse steder og starte en bl�ser hvis en af dem bliver for varm. Samtidig med skal der v�re en lysstyring som jeg gerne ville have til at k�re med en encoder og et PWM
output. Men problemet er at n�r arduinoen udregner de 4 temperaturer s� kan jeg ikke bruge en encoder . Den t�ller slet ikke. Jeg har s� sat en alm. pot ind og bruger den p� en analog input og ud fra den kan jeg sagtens styre output fint nok. men fra jeg drejer p� potten til der sker noget tager ca 1 sekund.

Nogen som har mod p� at fort�lle mig hvor det g�r galt henne i den her kode ?

C++ kode

 int tempMax = 30;
 int fanSpeed;
 int fanLCD;
 const int analogInPin = A4;  //  potentiometer 
 const int analogOutPin = 5; //  LED 
 
 int sensorValue = 0;        // value read from the pot
 int outputValue = 0;        // value output to the PWM (analog out)
 int lightLCD = 0;

   Serial.begin(9600);
   lcd.begin(20, 4);

     // read the analog in value:
   sensorValue = analogRead(analogInPin);            
   // map it to the range of the analog out:
   outputValue = map(sensorValue, 0, 1023, 0, 255);
