   Analog input, analog output, serial output
  

 Also prints the results to the serial monitor.
 
 The circuit:
 * potentiometer connected to analog pin 0.
   Center pin of the potentiometer goes to the analog pin.
   side pins of the potentiometer go to +5V and ground
 * LED connected from digital pin 9 to ground

// These constants won't change.  They're used to give names
// to the pins used:
const int analogInPin = A1;  // Analog input pin that the potentiometer is attached to
const int analogOutPin = A2; // Analog output pin that the LED is attached to

int sensorValue = 0;        // value read from the pot
int outputValue = 0;        // value output to the PWM (analog out)

void setup() {
  Serial.begin(115200); 

  pinMode(A0, OUTPUT);
  digitalWrite(A0, LOW);   // A0 is the - reference
  
  pinMode(A3, OUTPUT);
  digitalWrite(A3, HIGH);  // A3 is the + voltage
  
  pinMode(A1, INPUT);      // A1 is the sensor input

  pinMode(A2, OUTPUT);     // A2 has the LED
