Interfacing MC-38 Magnetic Sensor Anti Theft Alarm with Arduino

Step 1: Circuit

The following circuit shows how you should connect Arduino to MC-38 module. Connect wires accordingly.

Step 2: Code

Upload the following code to your Arduino. This code displays the status of the switch in the serial window.

const int magnet_switch = 2;     // Magnet switch
const int ledPin =  13;      // LED pin

void setup() {
  // initialize the LED pin as an output:
  pinMode(ledPin, OUTPUT);
  // initialize the pushbutton pin as an input:
  pinMode(magnet_switch, INPUT_PULLUP);

  Serial.begin(9600);
}

void loop() {
  if (digitalRead(magnet_switch) == LOW) {
    Serial.println("Switch Closed");
    digitalWrite(ledPin, HIGH);
    while (digitalRead(magnet_switch) == LOW) {}
  }
  else {
    digitalWrite(ledPin, LOW);
  }
}
