Abstract: As the rate of advancement of technologyis at tremendous rate and every technical System is almost working with the useof Remotes. In order to avoid separate remotes for different devices, we arekeen to make a sound operated system which will be able do all the functionsprovided by these remotes. It is possible to control the digial televisions,audio devices, personal computers and even lighting installations by SoundOperated System.Today we all are using mobile phones, and in eachmobile device there is one common communication link.
It will eliminate the useof remote. Keywords: Bluetooth, Sound based, Arduino, Android app. I. Introduction As the name suggests, theproject mainly focuses on controlling the electrical loads with help ofBluetooth input. However, it is also beneficial for physically disabled peopleas well as to aged people. It makes possible for them to control loads withoutphysically moving anywhere.
The Bluetooth devicereceives input signal from Android device. Microcontroller and the Bluetoothdevice are interfaced. Bluetooth receiver takes the commands from themicrocontroller and reacts accordingly. Relay driver IC is used. It regulatesthe loads.
Relays manage traffic between control unit and electrical load unit.Thus, systemhas many applications for regular homes as well as for industrial setups. Thesystem consists step down transformer in the power supply setup section. It isusually of 230/12V which step downs the voltage to 12VAC.For its DC conversion,A bridge rectifier is employed. Capacitive filter is needed to regulate supplyto +5V which is demanded by microcontroller and operation of other components,in order to remove ripples.

Medium through which devices communicate is calledBluetooth. We will be using this Bluetooth media to operate all electronicdevices which work via use of Sound operated system.Remoteoperation is achieved by any smart-phone or Tablet with Android OS, upon a GUI(Graphical User Interface) based voice operation. The transmitting end uses anAndroid application for the voice commands that are transmitted to digitalbits.
At the receiver end, these commands are used for controlling the homeappliances on and off.At the receiving end, the appliances are driven by powerTRIACS through opto isolators that are interfaced to the microcontroller. The project iscentralized on the voice controlled home automation system. It basicallyprovides the facility to control the home appliances via voice commands givenon Android device.
Here. an appliance can be turned on or off through the relay,which is controlled by an Arduino Mega board. Android app’s modification ispossible to add or modify the functions as well. II. LITERATURE SURVEY In earlier system, the devices were controlled bymanual operation.
A person was supposed to go near to the switch or the deviceto switch ON or OFF the device. There are couple of protocols present in marketbut either these protocols lake compactness, have unfriendly interfaces, notpractical to implement or consist some other bugs. The proposed projectminimizes all the errors seen in previous protocols.
It provides simple userinterface. It uses a remote control device called personal universal controllerwhich provides ability to interfaces to adapt complex appliances. With the help of LIRC 2 7 you candecode any infrared remote control codes and any Android phone can be convertedinto a remote control, so totally removing the need of remote controls. Theonly limitation with this approach is that the android phone should have aninfrared port with it. The infrared remote control has the performance of thehigh signal to noise ratio, strong anti-interference, reliable transmission ofinformation, low power and cost, therefore it is widely used in home appliancesmore or less.
The elevation inearlier years in natural philosophy andcommunication, computing and knowledge technology domain hasresulted, that we will generate the energyby exploitation renewable energy sources. For management of homeequipments we will use this energy. However, thepresent systems don’t permit a user tourge a practicableness to actively mitigate theability consumption of home equipments. within the earlierdays, the electrical home equipments will be controlled andmonitored with the assistance of homespun power cablesby exploitation power line communication technology.But, currently days a ZigBee technology isemployed for the electrical home equipmentsfor dominant and observation for a lot of probablethan before. This paper describes the methodology of renewableenergy based mostly home automation withinwhich 2 things area unit take into accountone is energyconsumption and another is energy generation.
In this, ZigBee isemployed for observation energy consumption of home equipmentsand power cable communication (PLC) isemployed to observation energy generation. Then home servercollects the energy consumption information and energygeneration information and analyzes them for energy approximationand management the house energy utilization schedule to slumpthe energy price. Then energy information of home serversevaluates them, and generates helpful appliedmath examination info mass by the remote energy managementserver. The system provides a lot of economical energysaving and lead to home energy price reduction.
16 The high energy required by home appliances (likewhite merchandise, audio/video devices and communication equipments) andaircon systems (heating and cooling), makes our homes one of theforemost essential areas for the impact of energy consumption on naturalsurroundings. AIM for the design of a system whichcan minimize energy waste in homeenvironments efficiently managing devices operation modes. Inour style we have a tendency to tend to use awireless device network to watch physical parameters (likelight-weight and temperature) in addition as a result of thepresence of users reception and in each of its rooms. so as tooptimize energy consumption and pricewhereas guaranteeing thedesired comfort level. once users amendment theirhabits as a results of unpredictable events, the system is in aposition to note wrong predictions analyzing in realtime data from sensors and to changesystem behaviourconsequently. Parameters that may stop the introduction of homeautomation systems for energy saving into the mass market. 17 III. METHODOLOGY This section presents the steps involved in the implementation of thisproject.
Initially, a block diagram was finalized on what components will beused for this idea. Later, a software platform and flow of software was decidedand worked on. These are described as following. Fig.3.
1 Block Diagram The first stepfor this project is getting the project title and objectives. Discussion withthe supervisor was made to find the most suitable title for this project. Theselection of suitable project title is necessary because the project title willgive the first impression on the project to be developing as a whole. After thesuitable project title was chosen, the next step is conducting literaturereview before writing the project proposal. All the information needed tocomplete this project is gathered and studied by reviewing journals, articles,books and previous research that related to this project. In this project, a simple VoiceActivated Home Automation system is designed. Voice commands are used tocontrol different appliances. Let’s move on to working of the project.
All theconnections are implemented from the circuit diagram above. After making thenecessary connections, we have to switch on the power supply to the circuit.Now, first of all, we need to install above mentioned android app in the smart-phone.The home screen of the app is as shown. After that, android device’s Bluetoothis paired with the HC-05 Bluetooth Module.
Now Bluetooth module is needed toconnect with phone. To connect it, select the mode “Connect Robot”and choose the needed Bluetooth Device. Once successfulconnection is made, device can transmit data. For giving commands, touch thepress button with microphone icon on the app interface.
The reason forpadding the ‘*’ and ‘#’ at the begging and end of the string is to identify thestarting and ending of the message. We are able to delete the ‘#’ fromthe string but left out the ‘*’ in order to identify the starting of the string.Strings are predefined. It is for identifying and act to the received message.It makes corresponding action according to match such as turning on or turningoff the load.
We have used the following commands: “turn on AC”, “turn off AC”, “turnon light”, “turn off light”, “turn on TV”, “turn off TV”, “turn on fan”, “turnoff fan”, “turn on all” and “turn off all”.The projectproposal was later ready before beginning theproject. each hardware and computer code analysis iscompleted to enhance the understanding so as tocomplete the project expeditiously. The functions of every part,tools and instruments required to be employed in this project are studied tocut back the time required forthe planning method. computercode analysis are done toincrease the understanding andavoid several mistakes throughout theprogramming method.

PROPOSED WORKSmart-phones and tablets such as Nokia’s Maemo (N900), Apple’s iOS and Google’s Android operating system can also beused as Voice Controlled System. A number of devices from vendors such as Samsung, LG and Nokia include a built-in IR port that can be used as a controller,while others require a physical attachment, or ‘dongle’, be connected on to thephone when used as a controller. The dongle is required to convert theelectrical control signals from the phone into infra red signals that arerequired by most home audio visual components for remote control. However itcan be implemented through system which doesn’t necessarily require dongle.Such systems use a ‘gateway’.
Gateway gets the incoming electrical signal viasmart-phone. Received signals are in the form of Bluetooth or WIFI and forwardthem on in infra red form to the components to be controlled. PROPOSED SYSTEMOur proposed system is a Voice Controlled System will operate via use ofBluetooth mobile application basically, t h e Graphical U s e r Interface (GUI)for the Voice Controlled System program is going to be develop by using android studio. The circuits wereconstructed from two modules, one to capture the signal and provide timingfunctions, and the second as transmitter placed somewhere near the targetequipment. The hardware was interfaced to mobile Bluetooth application on thecommunication port .The system is functional with almost every standardTelevision, DVD player, A.C.
