#MAKE A SIMPLE ANDROID APP BLUETOOTH#

The app on your smartphone sends data when you click on buttons or feed voice commands via Bluetooth in the mobile to Bluetooth module HC-05 connected with Arduino board.

#MAKE A SIMPLE ANDROID APP SOFTWARE#

MIT App Inventor software was used to create the Android app (.apk) for this project.

Arduino Uno is programmed using Arduino IDE software that you can download from. The software program for the home automation project(homeautomation.ino) is written in Arduino programming language called Processing. Vin is usually used to give input power, but since we are supplying 12V to Arduino using an adaptor, we can use Vin pin on Arduino to power the 12V relay module. Pins Vin and Gnd of the relay board are connected to pins Vin and Gnd of Arduino board, respectively. Pins 2, 3 and 4 are connected to the three relays (RL1, RL2 and R元) of the relay board. Pins Gnd and Vcc of the Bluetooth module are connected to Gnd and +3.3V of Arduino board respectively. In this home automation project circuit, Pins 10 and 11 of Arduino are connected to pins T XD and R XD of the Bluetooth module, respectively, as shown in Fig. The MCU onboard is programmed in Arduino programming language using Arduino IDE. It is very easy to use as you simply need to connect it to a computer using a USB cable, or power it with an AC-to-DC adapter or battery to get started. It is operated with a 16MHz crystal oscillator and contains everything needed to support the MCU. It consists of 14 digital input/output pins, six analogue inputs, a USB connection for programming the onboard MCU, a power jack, an ICSP header and a reset button. It is intended for artists, designers, hobbyists and anyone interested in creating interactive objects or environments.Īrduino Uno is based on ATmega328 microcontroller (MCU). Arduino Uno boardĪrduino is an open source electronics prototyping platform based on flexible, easy-to-use hardware and software. An 8-channel relay module is shown in Fig. It gets activated using 5V from Arduino, which, in turn, controls electrical appliances like fans, lights and air-conditioners. Relay provides complete isolation between the low-voltage circuit on Arduino side and the high-voltage side controlling the load. 3: Control panel on Android smartphone Relay moduleĪ relay allows you to turn on or turn off a circuit using voltage and/or current much higher than what Arduino could handle. The module runs on 3.3V to 5V power supply.įig. Using these features it can communicate with other Bluetooth-enabled devices like mobile phones, tablets and laptops.

4), which supports master and slave mode serial communication (9600-115200 bps) SPP and UART interface. 2: Connections for the appliances Bluetooth moduleīluetooth module used in this project is HC-05 (Fig. Connection details for each appliance are shown in Fig. The relay module and Bluetooth module can be, in turn, powered using a board power supply of Arduino Uno. Arduino Uno is powered with a 12V DC adaptor/power source. The number of channels depends on the number of appliances you wish to control. The home automation circuit is built around an Arduino Uno board, Bluetooth module HC-05 and a 3-channel relay board.

So you need not get up to switch on or switch off the device while watching a movie or doing some work. Commands are sent via Bluetooth to Arduino Uno. Presented here is a home automation project using a simple Android app, which you can use to control electrical appliances with clicks or voice commands. So it makes sense to use these to control home appliances. Nowadays, people have smartphones with them all the time.
