turn_on_led_seconds(num_seconds, pin_led) will turn on pin_led for num_seconds

:returns: integer of the time in seconds that pin_led was on for

turn_off_led_seconds(num_seconds, pin_led) will turn off pin_led for num_seconds

:returns: integer of the time in seconds that pin_led was off for

main() is the main function that will call other functions to implement the following:

1. turn on the LED for some amount of time.

2. turn off the LED for some amount of time.

3. repeat the above two steps 7 times in total

the above steps will generally be implemented by functions defined before the main() function.
