In this example we connect a tilt switch up to Pin 2 and connect an LED to pin 3, when we move the tilt switch the LED will light
Code
const int tiltPin = 2; // the number of the pushbutton pin const int ledPin = 3; // the number of the LED pin int tiltState = 0; // variable for reading the tilt switch status void setup() { // initialize the LED pin as an output: pinMode(ledPin, OUTPUT); // initialize the tilt switch pin as an input: pinMode(tiltPin, INPUT); } void loop(){ // read the state of the tilt switch value: tiltState = digitalRead(tiltPin); // check if the tilt switch is pressed. if (tiltState == HIGH) { // turn LED on: digitalWrite(ledPin, HIGH); } else { // turn LED off: digitalWrite(ledPin, LOW); } }
