==Introduction==
Arduino Relay Shield employs high quality relay with eight channels input and eight channels output. 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 and etc.<br>
The modularized design makes it easy to connect to Arduino expansion board. The output state of the relay is shown by a luminous diode for the convenience of actual application.<br>


==Specification==
* Control signal: TTL voltage
* Rated load: 
 10A 250VAC 
 10A 125VAC
 10A 30DC
 10A 28VDC
* Rated Through-current: 10A(NO)  5A(NC)
* Max Switching Voltage: 250VAC  30VDC
* Contact actuation time: ﹤10ms
* Definition of module pins: 
 i) Pin 1 -Pin 8----Controlling end
 ii) Power supply (VCC)
 iii) Ground (GND)

==Sample Code==
<pre>
int BASE = 2 ;  // I/O pin connected by the first relay
int NUM = 8;   //total number of all relays
void setup()
{
   for (int i = BASE; i < BASE + NUM; i ++) 
   {
     pinMode(i, OUTPUT);   //set digital I/O pin as output
   }
}

void loop()
{
   for (int i = BASE; i < BASE + NUM; i ++) 
   {
     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 ‘low’， i.e. turning on the relay gradually    
 delay(200);        //delay
   }  
}
</pre>
