Sample Code:

int ledPin = 13; // Connect LED to pin 13

int switcher = 3; // Connect Tilt sensor to Pin3

void setup()

{

pinMode(ledPin, OUTPUT); // Set digital pin 13 to output mode

pinMode(switcher, INPUT); // Set digital pin 3 to input mode

}

void loop()

{

if(digitalRead(switcher)==HIGH) //Read sensor value

{

digitalWrite(ledPin, HIGH); // Turn on LED when the sensor is tilted

}

else

{

digitalWrite(ledPin, LOW); // Turn off LED when the sensor is not triggered

}

}
