/****** SYSTEM REQUIREMENTS *****/
/****** SYSTEM REQUIREMENT 1 *****/
	/* The system should control a relay module connected */
	/* to digital pin D2 using the Relay library. The */
	/* relay on off same as switch on off at blynk */
/****** SYSTEM REQUIREMENT 2 *****/
	/* Create a system to manage a relay module on */
	/* digital pin D2 with the Relay library. The relay */
	/* should respond to a Blynk app switch, ensuring */
	/* synchronized on/off states for efficient remote */
	/* control. */
