Relay Datasheet.

A sample Arduino Code to operate this four channel relay mode is as follows:

int BASE = 2 ; // I/O pin connected to the first relay
int NUM = 4; //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
