Sample program for Arduino™

In this example, IN1 and IN2 are connected to Arduino™ digital

pins 4 and 5.

int IN1 = 4;

int IN2 = 5;

#dene ON 1

#dene OFF 0

void setup()

{

//initialize the relay

relay_init();

}

void loop()

{

//turn on RELAY_1

relay_SetStatus(ON, OFF);

//delay 2s

delay(2000);

//turn on RELAY_2

relay_SetStatus(OFF, ON);

//delay 2s

delay(2000);

}

//initialize the relay

void relay_init(void)

{

//set all the relays OUTPUT

pinMode(IN1, OUTPUT);

pinMode(IN2, OUTPUT);

//turn o all the relay

relay_SetStatus(OFF, OFF);

}

//set the status of relays

void relay_SetStatus(unsigned char

status_1, unsigned char status_2)

{

digitalWrite(IN1, status_1);

digitalWrite(IN2, status_2);

}
