I wanted to make it possible to control an arduino board from my phone.
So that I could control other devices.
the easiest way seemed to be using bluetooth.
but when I received the parts needed I found it want quite as simple as I had hoped.
And after looking on the Internet I didn't find much information to help.
so I have decided to write this guide to help other people that are thinking of doing the same thing.
Step 1: Parts needed
1 arduino board ( I used the duemilanvoe 328)
1 bluetooth serial board ( I used the sparkfun bluesmirf)
some pieces of wire
A computer with bluetooth or a usb bluetooth adaptor.
A pocket PC with bluetooth
the arduino enviroment software
and some serial terminal software ( I used putty)
Step 2: Wiring it all up
then I wired the tx on the module to the rx on arduino
the rx on the bluetooth to the tx on arduino
I protected the bluetooth module by sealing it with heatshrink.
I then connected +5v and 0v to the bluetooth board from arduino and supplied the arduino board with 5volts.
and pluged an LED in to socket pin 13 and ground to test it.
