Abstract – Remote is an essential component of electronic
then automatically creating an interface for controlling that appliance. With the help of LIRC [2] [7] you can decode any infrared remote control codes and any Android phone can be converted into a remote control, so totally removing the need of remote controls. The only limitation with this approach is that the android phone should have an infrared port with it. The infrared remote control has the performance of the high signal to noise ratio, strong antiinterference, reliable transmission of information, low power and cost, therefore it is widely used in home appliances more or less. In addition to utilizing in home appliances, it has been brought into the industrial control and so on. But the formats of infrared remote control protocol used are different between the different companies’ production, the consequence from this is that an infrared remote control device must be fit for the home appliances.
devices such as Television, DVD player, Air Conditioner (AC), etc. and used to operate that device wirelessly in a particular range. If a remote is misplaced it is difficult to find it, as well as only one person can use it at a time. This leads us to the designing of a remote which will be in one self’s mobile phone. We are developing the remote buttons on the android application, by which we will be able to ON/OFF AC or increase/decrease the temperature of AC. Here we will be using Bluetooth as a medium to interface between mobile phone and controller. The AC will be controlled using an android phone commands. The android application will be reprogrammable and tooling can be changed to provide multiple applications. Key Words: Android mobile phone, Bluetooth module HC-05, IR LED, IR receiver, AC remote, etc.
3. METHODOLOGY
1. INTRODUCTION
This section presents the sequence of completion of this project. Initially a block diagram was finalized on what components will be used for this idea. Later a software platform and flow of software was decided and worked on. These are described as follows.
Nowadays remote controller is available for every electronic device. But time is invested in search of it. So we can develop the remote on our smart phone screen by using android applications which indeed will be very useful for communication. The purpose of our research is to provide an Air Conditioner remote control architecture but with powerful computational platforms so that designer can focus and enjoy air conditioner without wasting time in search of remote. We can operate Air Conditioner by our mobile not only at home but also from outside. Total control will be there in our hands. This simple architecture is also useful for Education of android application and Arduino IDE programming because students can build their own Android application with low cost and use them as platform for experiments in several course.
3.1 Block diagram Block diagram is a basic flow diagram to explain the project. Here we can see that the Arduino Uno board is connected to the Bluetooth module directly. Arduino board is powered by using 5 V power supply. IR LED and IR receiver is connected on the transmitting and receiving terminals of the Arduino board respectively.
2. LITERATURE SURVEY
In earlier system, the devices were controlled by manual operation. A person was supposed to go near to the switch or the device to switch ON or OFF the device. Although many wireless protocols exist they fail to provide compactness and user friendly interfaces to the users. User can control appliances easily by his Smartphone via Bluetooth. It provides simple user interface. The personal universal controller (PUC) is a remote control device for improving the interfaces to complex appliances. The PUC engages in twoway communication with everyday appliances, first downloading a specification of the appliances functions, and
