ZARDUINO Project with Dave Houston:

LED Test: Blink 4 seconds HIGH-TRISTATE-LOW

/*
  Blink
  Turns on an LED on for one second, then off for one second, repeatedly.
 
  This example code is in the public domain.
 */

// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int led = 13;

// the setup routine runs once when you press reset:
void setup() {
  // initialize the digital pin as an output.
  pinMode(led, OUTPUT);
}

// the loop routine runs over and over again forever:
void loop() {
  digitalWrite(led, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(4000);    // wait for a second
  pinMode(led,INPUT);
  delay(4000);    // wait for a second  
  pinMode(led,OUTPUT  );
  digitalWrite(led, LOW);    // turn the LED off by making the voltage LOW
  delay(4000);               // wait for a second
}
