Outputs each group of 4 lines has. This project provides the solution to this problem by integrating all the electrical appliances to a control unit that can be operated by an Android application on a device Android smart phone or Tablet. The proposed system controls the electrical loads based on the data transmitted by the Android device. An Android application should be installed in users mobile or tablet to control the electrical loads. Using this Android application user can send the commands to the Bluetooth module to control the electrical loads. Wireless technology used in this project is Bluetooth.

Proteus for Circuit Diagram and SimulationAndroid Application installed on Android Device. Android Based Home Automation System Circuit Design. This project consists of a microcontroller, 1. LCD, 4 Channel Relay Module, Loads Light Bulbs are used in the demonstration and Bluetooth Module. Here, AT8. 9C5. 1 Microcontroller is used. It is an 8 bit microcontroller and it requires supply voltage of 5. V DC. Use 7. 80. 5 power supply circuit to provide 5. V DC to the microcontroller. We can use 9. V DC battery or 1. V, 1. A adapter to provide the supply to the circuit. For the above circuit additionally you need to connect reset circuit and crystal circuit to the controller to work properly. You can ignore these connections Power Supply Regulator, Crystal Circuit and Reset Circuit if you are using an 8. Development Board. In the above circuit, the LCD display is used to indicate the status of electrical loads and also used to display received data from Bluetooth Optional Feature. Here, the LCD Display is interfaced to the PORT1 of the microcontroller in 8 bit mode i. LCD are connected to PORT1. The three control pins of the LCD i. RS, RW and EN are connected to P3. GND and P3. 7 pins respectively. Also, a 1. 0K POT is connected to the Contrast Adjust pin of the LCD to control the contrast of the display. The TX and RX Pins of the Bluetooth Module are connected to the RXD and TXD pins P3. P3. 1 of the microcontroller. VCC pin Pin 4. 0 is connected to the 5. V and GND pin Pin 2. The Microcontroller communicates with Bluetooth Module using serial communication UART protocol. Use a baud rate of 9. Bluetooth. If you want to change the Bluetooth name and password then you need to use Bluetooth AT commands. Below are the few Bluetooth AT commands AT  Responds OK. Used to test the Bluetooth moduleATRESET  Responds OK. Used to reset the moduleATNAME  Responds with the module name. ATNAME  lt name Responds OK. Name should be less than or equal to 2. ATPSWD  Responds with the existing password. ATPSWD lt password Sets module pairing password. To know about all the Bluetooth AT commands refer HC 0. Embedded Bluetooth Serial Communication Module AT command set. Electrical loads like Lamp and DC motor are connected to the P0. P0. 3 Pins through the 4 Channel Relay Module. Here, relays are used to switch AC loads using small DC voltages. NPN transistors are used to drive the relays. If you are using a relay module, then transistor and other important components to drive the relay are already embedded on the module itself. NOTE The Circuit Diagram shows connections of only one load. But the connections to the other loads can also be made in a similar fashion. Algorithm for Bluetooth Controlled Electronic Home Appliances Initialize the LCD and UART protocol. Now read the data from Bluetooth module. Display the received data on LCD. Compare the received string with predefined strings and accordingly switch the electrical loads. Display the status of electrical loads on LCD. Android based Home Automation System Circuit Simulation Video. Windows Xp Media Center Edition 2005. Watch the following output video of home automation system using android applications. How Bluetooth Controlled Electronic Home Appliances Circuit WorksWrite the program to the project in Keil software and create. Burn program to the controller with help of 8. Programmer and Willar Software. Now, give the connections as per the circuit diagram. While making the connections, ensure that there is no any common connection between DC and AC supplies. Use 5. V power supply circuit to provide regulated 5. V DC to the microcontroller. Switch on the both AC and DC supplies. Now relay output pins gets 2. V. So, do not touch the load connected pins. Install the Bluetooth Controller application on your Android Device Mobile Phone or Tablet from the following link https play. BT hlen. Now pair the Android device with Bluetooth module. Configure the Bluetooth Controller App as per the 8. Program. Send data to switch ON or OFF the electrical loads. Related Post Also read the post RF remote control for Home Appliances.
