Android Arduino Bluetooth HC-05 - Controlling Arduino Over Voice and Buttons in App

Hey this instructable is about Android - Arduino Connection and Controlling Arduino over Voice and Buttons in Android App, Have Fun Making it and Lets us Know How you did and any Suggestions @ [e-mail]

For our Android App BlueUino in Play Store

Step 1: Requirement

Requirement:

1. Arduino Uno/Mega/Mini/Nano

http://www.amazon.in/gp/product/B008GRTSV6/ref=as_...

2. Bluetooth HC-05

http://www.amazon.in/gp/product/B00R95Y0AK/ref=as_...

3. Channel Relay

http://www.amazon.in/gp/product/B00YY0SYFU/ref=as_...

Step 2: Connections

Connection as Shown in Image:

Arduino Pin ==> HC-05

Pin-RX (0) Pin ==> TX

Pin- TX (1) Pin ==> RX

GND ==> GND

VCC ==> VCC

Step 3: Coding and Stuff

//Note:- Use only non 0(Zero) Integers as Code <br>
#define Relay1  13
#define Relay2  12
#define Relay3  11
#define Relay4  10
#define Relay5  9
#define Relay6  8
#define Relay7  7
#define Relay8  6

      Serial.println("Device 5 OFF.");
    }
    if (incomingByte == 12) {
      digitalWrite(Relay6, HIGH);
      Serial.println("Device 6 ON.");
    }
    if (incomingByte == 11) {
      digitalWrite(Relay6, LOW);
      Serial.println("Device 6 OFF.");
    }
    if (incomingByte == 14) {
      digitalWrite(Relay7, HIGH);
      Serial.println("Device 7 ON.");
    }
    if (incomingByte == 13) {
      digitalWrite(Relay7, LOW);
      Serial.println("Device 7 OFF.");
    }
    if (incomingByte == 16) {
      digitalWrite(Relay8, HIGH);
      Serial.println("Device 8 ON.");
    }
    if (incomingByte == 15) {
