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
}


FAQ

Q1. Dear Sir/Madam, I'd like to know what angle does this tilt sensor trigger? How sensitive is it? Can the tilt angle trigger be adjusted?

A. It's just a simple digital tilt sensor, if the sensor are not placed on a strict flat surface, the little steel ball in the green tube will slip to one end of it, so it will output 0 or 1 digital signal, that's why we call it a "Switch". Actually strong vibration can effect it's output, but generally speaking, it's about 3 degree to make it slip from one side to the other side. Then you could know that its tilt angle could not be adjusted.
