About: An electronic engineer

This Project is about interfacing a bluetooth module with Arduino and android mobile to activate lights and fan in a room using voice control.

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Components Used

1. Arduino UNO

2. Bluetooth HC-05

3.Bread board

4. Few jummper wires

5. Relay

6. Multistrand wire for AC supply

Step 2: Wiring Connection

1.Give connection as Per circuit diagram

2.Connect the TX of Arduino to RX of bluetooth and RX of Arduino to TX of bluetooth

3.Give 5V supply to bluetooth module and ground it.

4.Connect relay1 to Digitalpin2 and relay2 to Digitalpin3 of the Arduino

5.Then give the AC supply to the relay as required

Step 3: Program Uploading

1.Upload the program to the Arduino uno

2.If required for more relay connection than just initialize an relay in the program and do a simple if else condition as required.

Step 4: About Voice Control

1.Here I am using bluetooth to send voice commands from my phone

2.The APK I am is AMR_Voice which may not be available in Playstore I will attach it with the instructable.

3.You can download the APK form here however it needs internet to decode voice into text.

I did not watch the video, I pretty much never do on instructables; so this comment is limited to the text. ( I did however, download and read the code, { who is E-Guy ? } )

In the text there is not schematic or code for voice recognition, this is apparently all done by the phone and perhaps the cloud.

In a system like this, that part of voice recognition is the heavy lifting. I think the text should discuss it. What do you think?
