Example Code for Arduino-LED Control

Wiring Diagram

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
}
