Hello, im planning to get an arduino uno, a 5v relay 2 channel, and a bluetooth module. I want to make a light/fan working on AC to turn On and Off with my android. Can u help me with this project? Am i getting all the required tools i should be getting? Im totally a newbie i ned help with programming aswell.
-Thanks
I think you should properly research what you want to do. If you want to have both on/both off, I think you can do it without an Arduino.
If you want both/one/other/none, i.e. separate control of fan and light, an Arduino may be usefully employed but it might still be better to find another way. Ironically, using two Arduinos may be a better idea than one with a phone.
You might find the following background notes useful for the bluetooth part.

no i mean i want to use a relay and control a fan and a light in my room using bluetooth connected with an arduino uno. I want your help
I've somehow gotten to connect the arduino, a b.t module, and a relay. Im going to use an android to turn on and off the relay. Can anyone help me in generating an arduino code for it? Pleasee.

Does your android dream of electric sheep?
refer: ttp://m.instructables.com/id/Arduino-Bluetooth-Controlled-Desk-Lamp-With-Relay-/?ALLSTEPS
this is the method as per this link:
BT module Vcc - Arduino 5vBT module
GND - Arduino GND
BT module RX - Arduino TX
BT module TX - Arduino RX
Relay module signal pin - Arduino pin 3
f i want to connect a bluetooth module, arduino and a 5v relay is the above method correct? if it is where will the relay get its power? if its wrong kindly provide me the method to link them.
?
If you want someone to write code for you please ask in the Gigs and Collaborations section of the Forum and be prepared to pay.
If you want to learn to program yourself the examples that come with the Arduino IDE are a good place to start. There are also many online tutorials
...R
Nothing can be wrong because you have not provided any code or hardware schematic.
Cannot say you are helping us help you ...
So in summary, it is definitely module to connect a Bluetooth module over Rx and Tx and an Arduino module (would be really nice to know WHICH ONE you are using) can definitely turn a relay on or off, perhaps through a transistor, depending on the relay...
If someone has posted an Instructable, it is likely that their code and schematic does work.
If you put all of your hardware together and experience any issues with your code , let us know.
At this time, without any code, we are not able to assist ...
Please post your code as per the instructions as described here :
http://forum.arduino.cc/index.php?topic=149014.0
NOTE : It looks like you have posted the same similar request FOUR TIMES today.
Please POST A SINGLE REQUEST and people will get back to you.
It is totally useless to post the same request four different times.
Thanks a lot for your understanding
Thanks and best regards,
dan
We will often spend hours assisting but not spend minutes doing your job for you.

this is pretty simple.
google arduino and relay. you will find code.
google a b.t module arduino you will find code
google android arduino you will find code.
there we helped you generate code.

To insert an image you need to use the URL of the image.
To insert a link use the "Insert a link" icon and don't add extra spaces to the URL. It's as if you didn't want us to find it.
A good place to start learning to do this is to learn to turn a LED on and off. Then learn to control the LED through the terminal.
Once you can turn a LED on and off from the serial terminal, you'll be very close to completing your project.

i mean how do i connect all this stuff togther? im confused i got that image from google. and idk if that arrangement is correct? 
It looks ok but the pin markings of the BT module are not shown.
Rx and Tx of the Arduino go to Tx and Rx of BT module. IE, they cross over.

will the arduino give 5v to each i.e the bt and the relay without burning out if i use that approach?
