Example Arduinio Sketch


int led = 13;//LED pin
int sensor = 3; //sensor pin
int val; //numeric variable
void setup()
pinMode(led, OUTPUT); //set LED pin as output
pinMode(sensor, INPUT); //set sensor pin as input
void loop()
val = digitalRead(sensor); //Read the sensor
if(val == HIGH) //when magnetic field is detected, turn led on
digitalWrite(Led, HIGH);
digitalWrite(Led, LOW);
