Package Includes:
1 x KY-003 Hall Effect magnetic sensor module


KY-003 Hall magnetic switch

int Led = 13 ; // define LED Interface
int SENSOR = 10 ; // define the Hall magnetic sensor interface
int val ; // define numeric variables val

void setup() {
  pinMode(Led, OUTPUT) ;    // define LED as output interface
  pinMode(SENSOR, INPUT) ;  // define the Hall magnetic sensor line as input

void loop() {
  val = digitalRead(SENSOR) ; // read sensor line
  if (val == LOW) { // when the Hall sensor detects a magnetic field, Arduino LED lights up
    digitalWrite(Led, HIGH);
  } else {
    digitalWrite(Led, LOW);
