Exercise Hint #1

Traffic Light sequence:


Red > Green > Yellow > Loop


Red takes the longest time

Yellow takes the shortest time

Green's time is between the duration of red and Yellow

Exercise Hint #2

To setup for all LED, repeat exercise from activity 1

Exercise Hint #3

Declare the states of all LED between delays in void loop.


Example:

void loop( ) {

digitalWrite (LED1, LOW);

digitalWrite (LED2, LOW);

digitalWrite (LED3, HIGH);

delay(1000);

digitalWrite (LED1, HIGH);

digitalWrite (LED2, LOW);

digitalWrite (LED3, LOW);

delay(1000);

}
