/* BLINKING LED | |||
* | |||
* Demonstrates how to make a LED connected to digital pin 4 | |||
* blink in an interval of 1 second. | |||
* | |||
* You could also use the internal LED on pin 13. This | |||
* LED is mounted onto the board with a resistor in between, | |||
* so whenn connecting a LED to pin 13 we don't need an extra | |||
* resistor. | |||

// set the LED pin to HIGH (+5 Volts) | |||
digitalWrite(ledPin, HIGH); | |||
// wait for 1000 milliseconds = 1 second | |||
delay(1000); | |||
// set the LED pin to LOW (0 Volts) | |||
digitalWrite(ledPin, LOW); | |||
