Arduino koda piemērs

// define constants
const int sensorPin = 8;
const int ledPin = 7;
// define variable
int sensorState = 0;

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital sensorPin as an input and ledPin as output
  pinMode(sensorPin, INPUT);
  pinMode(ledPin, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  // read sensorPin value and assign it to sensorState variable
  sensorState = digitalRead(sensorPin);
  // set ledPin to sensorState value
  digitalWrite(ledPin, sensorState);
  // pause for 100ms
  delay(100);
