Read analog pin

My code is :

int analogPin = 1;
int val = 0;

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

void loop() {
  val = analogRead(analogPin);    // read the input pin

  Serial.println(val); 
  delay(100);
}

And the schematic is attach, but I don't know how do you want a schematic so I made this.
Thank you for your answer,
