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

ConnectionDiagram

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

}
