/****** SYSTEM REQUIREMENTS *****/
/****** SYSTEM REQUIREMENT 1 *****/
    /* The project must control a timer that starts when */
    /* the infrared sensor is in a low active state and */
    /* stops when the sensor returns to a low active */
    /* state. The timer must be displayed on the LCD */
    /* screen. */
/****** SYSTEM REQUIREMENT 2 *****/
    /* The timer state should be handled using a state */
    /* machine. Furthermore, an explicit function called */
    /* 'resetTimer' needs to be implemented to reset the */
    /* counter and state of the state machine. */
/****** END SYSTEM REQUIREMENTS *****/
