1. PCB DIAGRAM

• A printed circuit board, or PCB, is used to mechanically support and electrically connect electronic components using conductive pathways, tracks or signal traces etched from copper sheets laminated onto a non-conductive substrate.

• When the board has only copper tracks and features, and no circuit elements such as capacitors, resistors or active devices have been manufactured into the actual substrate of the board, it is more correctly referred to as printed wiring board (PWB) or etched wiring board.

2. CIRCUIT DIAGRAM

1.)The above diagram shows a microcontroller , 3 relays, a Bluetooth serial module and a lamp.

2.) The microcontroller is a PIC microcontroller and it requires a 5 volt DC supply.

3.) We can use 9V DC battery or 12V, 1A 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.

.

4.) Bluetooth module TX and RX pins are connected to the RXD and TXD pins of controller

6.) Vcc pin is connected to the 5V and GND pin is connected to ground. Controller communicates

with Bluetooth module using serial communication (UART protocol).

7.) Use a baud rate of 9600 to communicate with Bluetooth. If you want to change the Bluetooth

name and password then you need to use Bluetooth AT commands.

PRINCIPLEThis project aims at controlling home appliances

using Bluetooth serial module.

Bluetooth has always been meant for sharing purposes.

But this project adds an advantage of bluetoothby controlling home appliances.

Bluetooth serial module is connected to the microcontroller circuit and it is further connected

to the relay.

We connect appliance to the relay and operate it.

How Bluetooth Controlled Electronic Home Appliances Circuit Works?

1.) Write the program to the project in Kiel software and create hex file2.) Burn program to the controller with help of flash magic.3.) Now give the connections as per the circuit diagram.4.) While making the connections, ensure that there is no any common connection between DC and AC supplies.5.) Use 5V power supply circuit to provide regulated 5V DC to the microcontroller.6.) Switch on the both AC and DC supplies.7.) Now relay output pins gets 12v so do not touch the load connected pins.8.) Install Bluetooth apk file in android device.9.) Now pair android device with Bluetooth module.10.) Send data to switch on the electrical loads.

BIOMETRICS

BIOMETRICS

• The BIOMETRICS is a part of automation , it is a security system that can unlocked only by finger prints or eye retina saved in system.

• Master touch and LCD used security system is also a part of automation.
