WARNING : THIS PROJECT WILL CAUSES EXCITEMENT WHICH MAY BE INJURIOUS TO HEALTH.

So here I am with another fun Instructables controlling led through voice using Arduino via Bluetooth module (HC 05). So this Instructables can be treated as the basics of home automation system. This will be useful if you are getting started with Arduino and will help out if you are making a Bluetooth controlled home automation system.

If you don't have an idea about what is a home automation system is?

Home automation is the use of one or more computers to control basic home functions and features automatically and sometimes remotely. An automated home is sometimes called as a smart home. In the future instructables, I will show you how to setup a server to control the system.

I am going to explain you as simple as possible . If you feel difficulty in following feel free to PM i will be glad to help you out.

So let's get started!!!!!!!

Step 1: TOOLS REQUIRED :-

The list of components is quite simple, all you need for this project is -

  • Arduino uno
  • Breadboard
  • Jumper wires
  • Bluetooth module
  • 5 led (different colors)

No soldering skills are required, as we will be using a breadboard.

Step 2: CONNECTING ELECTRONICS :-

We have to connect Bluetooth module to Arduino uno :

  • Vcc pin to 5V of Arduino
  • Ground pin to Ground pin of Arduino
  • Rx to Tx pin of Arduino (D0)
  • Tx to Rx pin of Arduino(D1)

Now it's time to connect the LEDs. Bend the cathode of the LED in such a way that cathodes of all LED should be placed in same row (as in picture 3). Now connect the Annode of all led to random digital pins ( I have connected to D3, D4,D5,D6,D7,D8)

See so simple the construction was, isn't it? Now lets start programming Arduino.

Step 3: CODING :

Time to upload the code, the code or program can be found in the attachments, download it or copy it and paste it in the ARDUINO IDE. The Arduino IDE can be found in the downloads section of the Arduino Home Page.

If you are running windows you need to install the drivers which can be found in the root of the Arduino IDE directory, feel free to modify the program or change it as you like.

Step 4: PAIRING DEVICE :-

How to control led with voice ??

Here you go with answer :-

  • Go to Android Playstore and download a application called AMR voice

  • Enable your Bluetooth

  • Click connect and pair with the Bluetooth module

  • Now enjoy your basic home automation project.

So I hope you enjoyed this instructable. follow me for home automation project and Arduino project. I will catch you with another interesting instructables.

helped alot..<br>thank u...
<p>It was a nice project for learning how to use a bluetooth module before. Thanks! The only problem was the application that was named above didnt work on mine. App understood what i said but there was no feedback from the leds. I used &quot;Bluetooth Terminal &quot; instead which worked fine.</p>
Tq sir i am a beginner ..wat if i need to connect a little fan..lite..motor for door ..wat modifications i need to undergo...how to select those fan ..lite...motor with respect to the compatible volttages pls hlp me i am very much interested in it
<p>I'm also a beginner, but I'd like to point you in the direction of relay switches. They'll allow small voltages (from the audrino) to control larger ones (box fan, light, motor). Just watch the relays to make sure that you're buying ones with enough amperage for your purpose.</p>
please help me basically m a computer science student but m very interested in creating these projects.. but i dont know the basics of electrical board stuff and al
what is that adruino... where do we get that.. how much it will cost
