Power Cables and Lamp sockets

Android device

Bluetooth Low Energy (BLE) Module (Generic)

Story

Hello world! Today I made a voice control and remote control app combined. In my opinion this is the best one I made and I'm going to use it in my home myself, also check out the others apps I made.

I will also put the commands in the tutorial as a text file and in the tutorial itself. You can control your home with Buttons or Voice with this app.

Follow the next steps for the code, app, parts list and schematic. If you want the Source just contact me!

Step 1: Parts list + Android APP

Just connect it as the schematic and everything should work. Also make sure not to have the Bluetooth connected when uploading the code!

DOWNLOAD THE APP ON GOOGLE PLAY

Parts list.

Arduino Uno, Any copy will do.

8 Channel relay, You can use 1 Channel Relays if you like. But I go for the 8.

HC-06 Bluetooth module.

Jumper wires set MM/FF/MF

Power Cables and Lamp sockets (optional to test relays)

Android phone + the APP.

The Commands in english

All on / all off

livingroom on / livingroom off

kitchen on / kitchen off

balcony on / balcony off

bathroom on / bathroom off

bedroom on / bedroom off

attic on / attic off

barn on / barn off

closet on / closet off

To change baudrate, name and pin of your Bluetooth device follow step 2. (optional)

Step 2: How to change the name of your HC-06

What is needed?

1 x USB to TTL microcontroller programmer to connect to your HC-06

How to connect the Programmer?

VCC to VCC

GND to GND

RXD to TX

TXD to RX

Lets get started...

Connect the USB TTL programmer to the HC-06

Plug in the USB and open up The Arduino IDE

Open the serial monitor.

Type "AT" without quotes. You should see a respond in the Serial monitor saying "OK"

Type "AT+NAMExyz" Sets the module name to “xyz” (Replace xyz with the name you want.) response should be OKsetname.

Type "AT+PIN1234" Set the pin to 1234 (replace 1234 with your desired pin) respond should be OKsetPIN. For more info on changing baudrate etc. I included a PDF file. Good luck!

/*
Author: Danny van den Brande. Arduinosensors.nl. BlueCore Tech.
This code is written for my home voice control app.
The app simply reads the bytes @ case, 1,2,3,etc.
You can control 8 relays trough your phone with this.
You can add any device you want to the relays.
