Code

/* Blink Turns on an LED on for one second, then off for one second, repeatedly. The circuit: * LED connected from digital pin 13 to ground. * Note: On most Arduino boards, there is already an LED on the board connected to pin 13, so you don't need any extra components for this example. Created 1 June 2005 By David Cuartielles http://arduino.cc/en/Tutorial/Blink based on an orginal by H. Barragan for the Wiring i/o board */ int ledPin = 13; // LED connected to digital pin 13 // The setup() method runs once, when the sketch starts void setup() { // initialize the digital pin as an output: pinMode(ledPin, OUTPUT); } // the loop() method runs over and over again, // as long as the Arduino has power void loop() { digitalWrite(ledPin, HIGH); // set the LED on delay(1000); // wait for a second digitalWrite(ledPin, LOW); // set the LED off delay(1000); // wait for a second }
