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);

}

}
