Reed Switch - Lighting LED with a magnet

Arduino
#define Led A3
#define Reed 13

void setup() {
   pinMode(Led, OUTPUT);
   pinMode(Reed, INPUT);
   Serial.begin(9600);
}

void loop() {
  Serial.println(digitalRead(Reed));
  if (digitalRead(Reed)==0 ) {
    digitalWrite(Led,HIGH) ; 
  else 
    digitalWrite(Led, LOW); 
  }
}

Hall Sensor - Lighting LED with a magnet

Arduino
#define Led A3
#define Hall A4

void setup() {
   pinMode(Led, OUTPUT);
   pinMode(Hall, INPUT);
   Serial.begin(9600);
}

void loop() {
  Serial.println(digitalRead(Hall));
  if (digitalRead(Hall)==0 ) {
    digitalWrite(Led,HIGH) ; 
  else 
    digitalWrite(Led, LOW); 
  }
}
