/****** SYSTEM REQUIREMENTS *****/
/****** SYSTEM REQUIREMENT 1 *****/
    /* The servo motor installed in the door will lock or */
    /* unlock based on the correct PIN code received by */
    /* the button. If the door is unlocked and the PIN is */
    /* correct, it will lock. If the door is locked and */
    /* the PIN is correct, it will unlock. */
/****** SYSTEM REQUIREMENT 2 *****/
    /* The webserver provides a web page about lock or */
    /* unlock state of the door. */
