Tilt switch module and a digital interface, built-in 13 LED build a simple circuit to produce tilt warning lamp 13 comes with digital interfaces of the LED,

   the tilt switch sensor interface to access digital 3,when the tilt open Off sensor senses a key signal, LED lights, otherwise off.

   Routines source code:

   int Led = 13 ;// define LED Interface

   int buttonpin = 3; // define the tilt switch sensor interfaces

   int val ;// define numeric variables val

   void setup()

   {

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

   pinMode(buttonpin, INPUT) ;// define the output interface tilt switch sensor

   }

   void loop ()

   {

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

   if(val == HIGH) // When the tilt sensor detects a signal when the switch, LED flashes

   {

   digitalWrite(Led, HIGH);

   }

   else

   {

   digitalWrite(Led, LOW);

   }

   }
