/****** SYSTEM REQUIREMENTS *****/
/****** SYSTEM REQUIREMENT 1 *****/
	/* DC motor is high until the IR sensor senses the */

	/* and the nuts fall in a cup placed in a disc(The */
	/* disc has 8 cups and a NEMA 17 stepper motor at */
	/* center). The disc should rotate 45 degrees after */
	/* the nuts */
