/****** SYSTEM REQUIREMENTS *****/
/****** SYSTEM REQUIREMENT 1 *****/
	/* The servo motor installed in the door will lock or */

	/* 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 */
