    Product Description:

    Linear Hall magnetic module and number 13 comes with LED build a simple circuit to produce magnetic field warning lamp. Use digital 13 interface comes with the LED. The linear Hall magnetic module connected digital 3 interfaces. When the linear Hall magnetic module senses detected the key signal. LED lights on, otherwise off.

    Routines source code:

    int Led = 13 ;// define LED Interface

    int buttonpin = 3; // define the linear Hall magnetic sensor interface

    int val ;// define numeric variables val

    void setup()

    {

    pinMode(Led, OUTPUT) ;// define LED as output interface

    pinMode(buttonpin, INPUT) ;// define linear Hall magnetic sensor as output interface

    }

    void loop ()

    {

    val = digitalRead(buttonpin) ;// digital interface will be assigned a value of 3 to read val

    if(val == HIGH) // When the linear Hall magnetic sensor detects the signal, LED flashes

    {

    digitalWrite(Led, HIGH);

    }

    else

    {

    digitalWrite (Led, LOW);

    }

    }
