// These constants won't change. They're used to give names to the pins used:
const int analogInPin = A4;  // Analog input pin 

int sensorValue = 0;        // value read from the pin

void setup() {
  // initialize serial communications at 9600 bps:
  Serial.begin(9600);
}

void loop() {
  // read the analog in value:
  sensorValue = analogRead(analogInPin);

  // print the results to the Serial Monitor:
  Serial.println(sensorValue);

  // wait 2 milliseconds before the next loop for the analog-to-digital
  // converter to settle after the last reading:
//  delay(2);
