RGB Module Combine with Arduino

Code #define red_led 5 // define arduino pin no 5 as red led
	#define green_led 6 // define arduino pin no 6 as green led
	#define blue_led 7 // define arduino pin no 7 as blue led
	#define Delay 1000 // define delay of 1 second
	int leds[3]={red_led, green_led , blue_led};
	void setup() {
	pinMode(red_led,OUTPUT); // set pin mode of all leds on OUTPUT
	pinMode(green_led,OUTPUT);
	pinMode(blue_led,OUTPUT);
	}
	void loop() {
	for (int i=0; i<3; i++) // run a loop to turn on and off all leds by turn
	{
	digitalWrite(leds[i],HIGH);
	delay(Delay);
	digitalWrite(leds[i],LOW);
	}
