This module 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.
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.

Sample code:
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
