You have two LEDs (let's say blue and red) attached to pin 4 and 5. Which code will make the LEDs blink at the same time. That is, we want both LEDs to be on at the same time for 1 second, and off at the same time also for 1 second until the board turns off.

Expert Solution
Step 1

Remember one thine here you want led to be blink together.

For on led need to be HIGH

delay(1000) is used to wait for 1 second.

For off led need to be LOW.

LED are at pin 4 and 5.

So First on the LED using

digitalWrite(5,HIGH);

digitalWrite(4,HIGH);

Now make then on for 1 second using

delay(1000);

Now turn off them using

digitalWrite(5,LOW);

digitalWrite(4,LOW);

Now make then off for 1 second using

delay(1000);

 

So Final Code is-

digitalWrite(5,HIGH);

digitalWrite(4,HIGH);

delay(1000);

digitalWrite(5,LOW);

digitalWrite(4,LOW);

delay(1000);
