Turns on an LED on for one second, then off for one second, repeatedly.

This example code is in the public domain.

*/

void setup() {

// initialize the digital pin as an output.

// Pin 13 has an LED connected on most Arduino boards:

pinMode(1, OUTPUT);

pinMode(2, OUTPUT);

pinMode(3, OUTPUT);

pinMode(4, OUTPUT);

pinMode(5, OUTPUT);

pinMode(6, OUTPUT);

pinMode(7, OUTPUT);

}

void loop() {

while(1)

{

for(int i=1; i<=7; i++)

{

digitalWrite(i, HIGH); // set the LED on

delay(100); // wait for a second

digitalWrite(i, LOW); // set the LED off

delay(100);

}

}
