Assignment 2.1

Post date: Jul 25, 2010 9:46:28 PM

Worked on this for awhile. It took some time figuring out how everything worked.

int led13 = 13; //sets variables for the sketch

int led12 = 12;

int led11 = 11;

int led10 = 10;

int led9 = 9;

void setup() {

pinMode(led13, OUTPUT); //intalizes digital pins 9-13 as outputs

pinMode(led12, OUTPUT);

pinMode(led11, OUTPUT);

pinMode(led10, OUTPUT);

pinMode(led9, OUTPUT);

}

void loop()

{

digitalWrite(led13, HIGH);// turn LED#13 on

digitalWrite(led11, HIGH);//turn LED#11 on

digitalWrite(led9, HIGH);//turn LED#9 on

delay(500); //wait for half a second

digitalWrite(led13, LOW);//turn LED#13 off

digitalWrite(led11, LOW);//turn LED#11 off

digitalWrite(led9, LOW);//turn LED#9 off

digitalWrite(led12, HIGH);//turn LED#12 on

digitalWrite(led10, HIGH);//turn LED#10 on

delay(500);//wait for half a second

digitalWrite(led12, LOW);//turn LED#12 off

digitalWrite(led10, LOW);//turn LED#10 off

digitalWrite(led13, HIGH);//turn LED#13 on

digitalWrite(led11, HIGH);//turn LED#11 on

digitalWrite(led9, HIGH);//turn LED#9 on

delay(500);//wait for half a second

digitalWrite(led13, LOW);//turn LED#13 off

digitalWrite(led11, LOW);//turn LED#11 off

digitalWrite(led9, LOW);//turn LED#9 off

digitalWrite(led12, HIGH);//turn LED#12 on

digitalWrite(led10, HIGH);//turnLED#10 on

delay(500);//wait for half a second

digitalWrite(led12, LOW);//turn LED#12 off

digitalWrite(led10, LOW);//turn LED#10 off

delay(500);//wait for half a second

digitalWrite(led13, LOW);//turn LED#13 off

digitalWrite(led12, LOW);//turn LED#12 off

digitalWrite(led11, LOW);//turn LED#11 off

digitalWrite(led10, LOW);//turn LED#10 off

digitalWrite(led9, LOW);//turn LED#9 off

delay(500);//wait for half a second

digitalWrite(led13, HIGH);//turn LED#13 on

digitalWrite(led12, HIGH);//turn LED#12 on

digitalWrite(led11, HIGH);//turn LED#11 on

digitalWrite(led10, HIGH);//turn LED#10 on

digitalWrite(led9, HIGH);//turn LED#9 on

delay(500);//wait for half a second

digitalWrite(led13, LOW);//turn LED#13 off

digitalWrite(led12, LOW);//turn LED#12 off

digitalWrite(led11, LOW);//turn LED#11 off

digitalWrite(led10, LOW);//turn LED#10 off

digitalWrite(led9, LOW);//turn LED#9 off

delay(500);//wait for half a second
