Introduction
what's the best way to detect the magnet? Use anther magnet. But it's not sensitive enough. You
have to feel it by youself.Right.This magnetic sensor knows whether there is a magnetic object
nearby or not. And it correctly tells you through ditigal output.See below picture for a quick demo!

SampleCode
int ledPin = 13; // choose the pin for the LED
int inputPin = 2; // choose the input pin
int val = 0; // variable for reading the pin status
void setup() {
pinMode(ledPin, OUTPUT); // declare LED as output
pinMode(inputPin, INPUT); // declare pushbutton as input
}
void loop(){
val = digitalRead(inputPin); // read input value
if (val == HIGH) { // check if the input is HIGH
digitalWrite(ledPin, LOW); // turn LED OFF
} else {
digitalWrite(ledPin, HIGH); // turn LED ON
}
}
