Analog Read Serial

 

/*
  AnalogReadSerial
  Reads an analog input on pin 0, prints the result to the serial monitor.
  Attach the center pin of a potentiometer to pin A3, and the outside pins to +5V and ground.
 
 This example code is in the public domain.

// the setup routine runs once when you press reset:

 

void setup() {
  // initialize serial communication at 9600 bits per second:
  Serial.begin(9600);
}

 

// the loop routine runs over and over again forever:

void loop() {
  // read the input on analog pin 0:
  int sensorValue = analogRead(A3);
  // print out the value you read:
  Serial.println(sensorValue);
  delay(1);        // delay in between reads for stability
