Step 1: Tools and Materials

Hardware :-

• Arduino / Arduino Clone
• A 5v TTL -UART Bluetooth module like : JY-MCU BT_BOARD (Cheaper) or Bluesmirf Gold/Silver.
• Five 5V SPDT relays like : 5V relay Prototype board or breadboard.
• Connecting wires.

Software :-

• Arduino IDE
• DIY smart home Android App

Arduino

If you are new to the Arduino, it is a small board, fully assembled with
a AVR micro controller. It is well suited for hacking and interacting with your environment. Many things that are hard with micro controllers are rather easy with Arduino. Some of the advantages:

no need for a separate programming device (programmer)
comes with an integrated development environment (IDE) runs on any platform, Windows, Mac, Linux. easy connection to your PC with USB hardware is open source (but the name Arduino is not) has a great community More information can be found at the official Arduino website.

Steps :-

1. Connect Your Arduino to Computer
2. Copy paste the Home_auto.ino file or open with the Arduino IDE
3. Upload the code to Arduino

Step 5: Step 5: Install the App

1. Connect Arduino to 9v battery or computer
2. Install the App in your Phone
3. run the application
4. allow the BT permissions ,
5. Type Your BT Module name (Normally HC-05)
6. Password = 1234
7. pair ok

In this Project I only use One Relay and there for we can control only one device , also we can add more relay module and control all of your home .

BE CAREFUL WHEN WORK WITH RELAY ITS 240V AC .
