//using A0 pin for first analog input
const int analogInPin1 = A0;
//and A1 for second analog input
const int analogInPin2 = A1;
//variables to store values from potentiometers
int p1value = 0;
int p2value = 0;

void setup()
{
  Serial.begin(9600);
}

void loop()
{
  //reading sensor value from first potentiometer
  p1value=analogRead(analogInPin1);
  //wrapping signal to a value between 0 and 255
  p1value=map(p1value, 0, 1023, 0, 255);
  //doing the same for second potentiometer signal
  p2value=analogRead(analogInPin2);
  p2value=map(p2value, 0, 1023, 0, 255);
  //displaying both values in serial output
  Serial.print("Potentiometer 1: ");
  Serial.print(p1value);
  Serial.print(", Potentiometer 2: ");
  Serial.println(p2value);
}
