/****** SYSTEM REQUIREMENTS *****/
/****** SYSTEM REQUIREMENT 1 *****/
/* When the EasyButton connected to pin D2 is */
/* pressed, the green LED connected to pin D4 shall */
/* blink precisely 10 times and then stop blinking, */
/* waiting for the EasyButton to be pressed again. */
/****** SYSTEM REQUIREMENT 2 *****/
/* Αφού η πράσινη λυχνία LED στον ακροδέκτη D4 */
/* ολοκληρώσει να αναβοσβήνει, η κόκκινη λυχνία LED */
/* στον ακροδέκτη D3 θα πρέπει να παραμείνει αναμμένη */
/* για 10 δευτερόλεπτα και στη συνέχεια να σβήσει. */
