Hi

I wanted to build a simple 2 channel bluetooth remote switch box. 
to allow me to remotely switch various devices on and off from my android phone.

The device had to be small easy to use and flexable enough to control anything I wanted.
some of the uses are controling my slr camera. and to switch on mains devices like lights.

parts needed.
1 arduino board ( i used a arduino nano as it was small and easy to attach to a computer to program)
1 relay board
1 bluetooth module (I used a jy-mcu module because it was cheap)
A plastic box to put everything in
A battery holder

I purchased the arduino board the bluetooth module and the relay board from ebay.
the plastic box and battery holder came from maplin.
be careful when purchasing the bluetooth module and check that its the board and bluetooth chip. as some on ebay are just the board without the bluetooth chip.

total cost was £20

Step 1: Connecting the arduino board to the computer

first of all I connected the arduino board to my computer usb port.
the board should light up.

now if you havnt got the arduino IDE software you should go here http://arduino.cc/en/Main/Softwareto download it
it should already be in the repositorys if you are using ubuntu linux.

when the software has been installed and opened. check the port and board setting are correct.
this will be under tools > board (select the board option to match your arduino board)
and tools > serial port. if this is greyed out you will have to check that your drivers are installed correctly for your board.

when the software is set up and communicating with your arduino. its time to write the code.
