		== '''Introduction''' ==
		<br>
		keyestudio Relay Shield employs high quality relay with four channels input and output.
		<br><br>
		It can be connected to 250V/10A AC element or 24V/10A DC element to the maximum, therefore, it can be used to control lights, motors, etc.
		<br><br>
		The modularized design makes it easy to connect to Arduino expansion board.
		<br><br>
		The output state of the relay is shown by a LED for the convenience of actual application.
		<br><br>

		== '''Specification''' ==
		<br>
		Control signal: TTL voltage
		<br><br>
		Active at HIGH level
		<br><br>
		Rated load: <br>
		* 10A 250VAC
		* 10A 125VAC
		* 10A 30DC
		* 10A 28VDC
		<br>
		Rated Through-current: 10A(NO) 5A(NC)
		<br><br>
		Max Switching Voltage: 250VAC 30VDC
		<br><br>
		Contact actuation time: ﹤10ms
		<br><br>
		Definition of module pins:<br>
		* i) Pin 1- Pin 4----Controlling end
		* ii) Power supply (DC12V)
		* iii) Ground (GND)

		int BASE = 2 ; // I/O pin connected to the first relay

		digitalWrite(i, LOW); //set digital I/O pin as ‘low’, i.e. turning off the relay gradually
		delay(200); //delay
		}
		for (int i = BASE; i < BASE + NUM; i ++) {
		digitalWrite(i, HIGH); // set digital I/O pin as ‘high’， i.e. turning on the relay gradually
		delay(200); //delay
		}
