Tasks second set 13 - 18

Tasks - Second set

13)  mostly on than off.
[...]
digitalWrite(led1, HIGH);
digitalWrite(led2, LOW);
delay(1000);
digitalWrite(led2, HIGH);
delay(500);
digitalWrite(led1, LOW);
digitalWrite(led2, LOW);
[...]
----------------------------------------------------------------
14)  now the opposite

[...]

digitalWrite(led2, HIGH);

digitalWrite(led1, LOW);

delay(1000);

digitalWrite(led1, HIGH);

delay(500);

digitalWrite(led2, LOW);

digitalWrite(led1, LOW);

[...]

15)  will send email

----------------------------------------------------------------

16) get one led to blink once then repeat the other infinitely 

//start of program

int powerOnLed = 13;

int blinkStatus = 12;

int num = 0;

void setup() {

  pinMode(powerOnLed, OUTPUT);

  pinMode(blinkStatus, OUTPUT);

  }

void loop() {

while(num = 0) {

  digitalWrite(powerOnLed, HIGH);

  delay(1000);

  digitalWrite(powerOnLed, LOW);

  num = num + 1;

  }

digitalWrite(blinkStatus, HIGH);

delay(1000);

digitalWrite(blinkStatus, LOW);

delay(1000);

}

--------------------------------------------------------------------

17) using the for loop SUCCESS!!

int ledPin1 = 13;
int ledPin2 = 12;
int t = 300;


void setup() {
pinMode(ledPin1, OUTPUT);
pinMode(ledPin2, OUTPUT);
}


void loop() {
int i = 0;
for(i=0;i<5;i++){
digitalWrite(ledPin1, HIGH);
delay(t);
digitalWrite(ledPin1,LOW);
delay(t);
}


digitalWrite(ledPin2, HIGH);
delay(t);
digitalWrite(ledPin2, LOW);
delay(t);
}

-----------------------------------------------------------------------------

18) same as above but different value

int ledPin1 = 13;
int ledPin2 = 12;
int t = 300;


void setup() {
pinMode(ledPin1, OUTPUT);
pinMode(ledPin2, OUTPUT);
}


void loop() {
int i = 0;
for(i=0;i<10;i++){
digitalWrite(ledPin1, HIGH);
delay(t);
digitalWrite(ledPin1,LOW);
delay(t);
}


digitalWrite(ledPin2, HIGH);
delay(t);
digitalWrite(ledPin2, LOW);
delay(t);
}
