  Watch Video instruction for this sketch: 

const int potPin = 39;// Analog pin

int potValue;// do not change
float voltage =0;// do not change

void setup() {
  // initialize serial communication at 115200 bits per second:

void loop() {
  // read the input on analog pin potPin:
  potValue = analogRead(potPin);
  voltage = (3.3/4095.0) * potValue;
  Serial.print(" Voltage:");
  delay(50); // delay in between reads for stability
