    Author:ASCAS Follow me on facebook.Hi I'm Angelo! I'm spending my last year of high school so I'll be gone for a while, preparing for college. Please understand that I can't assist you right now.BTW, you can follow me on facebook.

    Intro: DIY Android Home Automation BoxHere's a little show and tell of my Android controlled home automation box. It's a small extension box that's controlled by an Android smartphone. You can turn theindividual outlets on by tapping a button from the app or use the speech recognition app, found from my previous tutorial. I've teamed up with my friends and built acustom app for out home automation prototype project. My former classmate/ fellow ible member "treyes4" built something similar.

    __________________

    It's just a prototype so don't expect much from this version. I assure that next version would be explained more thoroughly.

    ________________

    I'll be gone for a while: I'll be posting a video once I get back from the international trade and business competition hosted by FedEx (school related). I posted this guideearly, since the home automation contest deadline is due today. There's a lot of unexplained areas in this guide, without the prior knowledge, this project would bedifficult to execute. Just ask questions below, I'll answer them through my phone. Once I get back, I'll edit and update this guide. Sorry for the inconvenience.

    Step 1: Bill Of MaterialsIf your having trouble in finding them, I'm sure RadioShack has all of them. If you want to buy online try searching on Amazon or DealExtreme.

    Thing that you'll need:

    - Android Phone & App

    - Arduino UNO (a clone works fine)

    - Low Power/ Switching Power Supply

    - Dot Matrix Solderless Breadboard

    - HC-05 Serial Bluetooth Module

    - 2N3904 NPN Transistor (5x)

    - 2.2k Ohm Resistor 1/4 (5x)

    - 6V Relays (5x)

    - Jumper Cables

    Step 2: Find A Good EnclosureI bought my enclosure from Alexan, a local electronics/ hobby store. This project is a prototype, the perfect enclosure would be an enclosure big enough to house anArduino prototyping board and a small switching-PSU.

    Step 3: Glue The Sockets TogetherAlign the outlets then use superglue to hold them temporarily. Hot glue can be used to strengthen the bond. After gluing, start to link a common rail. The linked rail work'slike a common ground although this is AC ~ so it's not.

    Step 4: Align & Measure The SocketsAlign the AC sockets together then acquire the dimensions of the array of sockets.

    Step 5: Transfer The MeasurementsTransfer your measurements by using a marker and ruler.

    Step 6: Grind And Drill The EnclosureUse your hacksaw or rotary tool to cut off the plastic that you've marked. Use a metal file to even out the edges.

    Step 7: Construct The Relay CircuitI constructed my DIY relay circuit. Obviously this is a complete prototype, I used a perfboard for mounting my components on. This is dangerous, exposed AC line cancause death through electrocution. Before attempting this project, be sure you're qualified to execute the task. My next version in the future would probably include solidstate relays mounted on a custom PCB.

    Step 8: Wire The PSUThe PSU will serve as your Relay and Arduino's power supply. I bought mine from ebay.

    Specs: 12v (1 Amp)

    Step 9: Upload The Sketch/*Paste this on your Arduino's IDE

    SoftwareSerial mySerial(2, 3); // RX, TX

    //these ladies shorten the script #define printer Serial.println #define reader mySerial.read

    works great.

    jueljp says: Jan 2, 2015. 1:01 PM REPLYany difference made to the electronics/coding?

    IshanP says: Feb 12, 2015. 3:26 AM REPLYi just wanted to know weather or not i can use 5 of these instead of soldering the relays

    jueljp says: Jan 2, 2015. 1:08 PM REPLYhow much watts per plug, i intend to use it to control some leds in my bedroom

    ASCAS says: Jan 22, 2015. 1:47 AM REPLYThat would depend on the relay that you have selected.

    LongJ says: Dec 30, 2014. 7:21 PM REPLYWoah .... Major rookie mistake here. You MUST put a diode across those relay coils or you are going to get a reverse polarity voltage spike back through thedriver transistor when the magnetic field of the relay coil collapses (This is the same effect switch mode power supplies use to generate lower, higher andopposite polarity voltages) A reverse polarity diode across the coil will spike that voltage to ground while doing nothing during normal operation. There areliterally hundreds of examples of how to do this on the internet.

    At least you have a transistor between the coil and the micro which helps protect the micro from the inductive kickback of the relay coil but you still need thatclamping/snubbing diode. Think of it as an insurance policies that costs just a few pennies

    ASCAS says: Dec 30, 2014. 9:25 PM REPLYI did actually, I added a 1N4007 rectifier on each relay although I forgot to document it here.

    LongJ says: Jan 21, 2015. 12:42 PM REPLYI'm not trying to be harsh here but you really should go back and add that to the documentation so those that don't know any better don't make themistake of leaving them out. Maybe even a short blurb explaining why this diode is important (I stock 1n4004 in the same bin as my relays becauseto me they are a set) You obviously have some skills, you just need to polish them and I certainly don't want to discourage you. One thing myGrandfather who was a Master Electrician taught me when I was still in high school and still serves me well (And I'm a BSEE) to this day is:

    The difference between a Master and a Journeyman is attention to detail .....

    LongJ says: Dec 30, 2014. 7:59 PM REPLYI'd like to add a couple of other tips. For those on 220/240V systems it doesn't matter which leg you switch but those of us in the US or other places with120V systems you should switch the black or Hot wire NOT the white or neutral wire which is a big no no and a violation of Federal (and State) ElectricalCodes. The reason being the white neutral wire is actually connected to the ground buss in the main service (breaker) box

    Even if you are using a non-conductive case please use a proper 3 prong grounded plug, ground your power supply's case and make sure the safetygrounds are run to all receptacles. Also I would put a fuse on the incoming AC line with a maximum 15 amp fuse.

    Stay safe and have fun!

    Nikus says: Nov 23, 2014. 4:12 AM REPLYI had the same problem but I solved it. You need to change in android code this:

    private static String address = "30:14:08:15:20:57";

    on address of your bluetooth module. You can check it in bluetooth settings on your phone.

    SOHAIBciit says: Nov 14, 2014. 9:08 PM REPLYHow to Install the android app.??

    ASCAS says: Oct 27, 2014. 11:08 PM REPLYBy following the given schematic.

    william.catchin says: Oct 27, 2014. 9:39 PM REPLYwhy the RX-TX pin of bluetooth module connected to pin 2-3 instead of TX-RX pin in arduino board?

    ASCAS says: Oct 27, 2014. 11:08 PM REPLYI reassigned the pins, because the BT module interferes with the arduino when I'm uploading a sketch.

    OhYeahThatGuy81 says: Sep 29, 2014. 5:59 AM REPLYVery nice!

    How does it feel to be a TV star?

    kimpoy.develles says: Sep 7, 2014. 9:28 PM REPLYHi Mr. Angelo!I'm planning to do your Home automation project as my school project..I'm wondering what sketch should be uploaded to the arduino board?its abit confusing because there are 3 sketches and I don't know which sketch should be uploaded..thanks :)

    Tezeusz says: Sep 21, 2014. 12:16 PM REPLYis not a sketch, it's a tab :)

    deba168 says: Aug 12, 2014. 9:25 AM REPLYCongrats Angelo :)

    ASCAS says: Aug 13, 2014. 3:06 AM REPLYThanks and congrats to you as well, my friend! :D

    DangerousTim says: Aug 5, 2014. 3:12 AM REPLYIt's an awesome project, but isn't it a little cumbersome to use your phone just to operate switches?

    ASCAS says: Aug 7, 2014. 2:01 AM REPLYMaybe, but the box does more than responding to app buttons. The PIR (motion) sensor is linked to my home automation box with an RF module. Everytime I enter my room, the box turns all the appliances on. The appliances turns off when the are no movements detected within the 30 minute timeperiod.

    Second, you can also download a voice activated app to control the home automation box via speech recognition. I have a separate tutorial of it.

    DangerousTim says: Aug 9, 2014. 3:01 AM REPLYAwesome ideas!!!

    critterfluffy says: Aug 7, 2014. 11:59 AM REPLYI can think of a couple really cool examples where this is useful and environmentally savvy. Feel free to steal these : )1.Add an RFID to a wireless charger station and when you phone detectsvia NFS, it turns the power to the charging pad on. Kills the energyvampire.2. When you phone attaches to home wifi, it turns on youroutside lights or when no phones are attached to home wifi it turns downthe heater/AC, water heater, and turns off all appliances after 5minutes.

    Basically giving your home a schedule and some sense ofwhere you are can allow for tons of variation that could reduce energyuse. Nice project.

    ASCAS says: Aug 7, 2014. 1:53 AM REPLYYou might want to wait for my next beginner friendly Home Automation project! :)

    mormor says: Aug 6, 2014. 7:35 AM REPLYVery neat, but you need to put in a reverse polarity diode in parallel with the relay coil to catch back-emf from the coil when the transistor opens the circuit,and you should probably also make better separation between live and the control circuit although as long as you are not connecting anything else to thecircuit directly when connected to the mains and it's in a closed box then you should be fine.

    I like the idea of using bluetooth to control it! :-)

    ASCAS says: Aug 7, 2014. 1:52 AM REPLYThanks! BTW, this is a prototype, of a larger home automation system that I'm working on. I'll add the diodes together with a custom PCB layout on myfinal project. :D

    johnybody says: Aug 6, 2014. 9:32 AM REPLYCool. How do you upload the app to your phone? Which software do you use?
