Automatic switching-on of LEDs with arduino bluetooth androi

There is a code which let to run LEDs with android using bluetooth module HC-05. LEDs switch one by one, it is ok.

But it nesessary to add the mode of switching of all diodes in automatic random mode.

The code wich I use is below. The code is working well.

int ledPin_1 = 9;

int ledPin_2 = 10;

int ledPin_3 = 11;

int ledPin_4 = 12;

int ledPin_5 = 13;

void setup() {

Serial.begin(9600);

pinMode(ledPin_1, OUTPUT);

pinMode(ledPin_2, OUTPUT);

pinMode(ledPin_3, OUTPUT);

pinMode(ledPin_4, OUTPUT);

pinMode(ledPin_5, OUTPUT);

}

void loop() {

if (Serial.available() > 0) {

int i = Serial.read()-48;

if (i == 1)digitalWrite(ledPin_1, !digitalRead(ledPin_1));

if (i == 2)digitalWrite(ledPin_2, !digitalRead(ledPin_2));

if (i == 3)digitalWrite(ledPin_3, !digitalRead(ledPin_3));

if (i == 4)digitalWrite(ledPin_4, !digitalRead(ledPin_4));

if (i == 5)digitalWrite(ledPin_5, !digitalRead(ledPin_5));

}

}

I think may be to use the code for random mode:

void randomLED()

{

int index;

int delayTime;

index = random(8); delayTime = 100;

digitalWrite(ledPins[index], HIGH);

delay(delayTime);

digitalWrite(ledPins[index], LOW);

}

This code separately is working good but i can’t bind it with bluetooth.

Please help.
