Hi guys. i currently have my arduino board working with a bluetooth modem, but this is too power demanding. does anyone know of any way to set up a wireless arduino board with radio frequency.
ideally i would need a RF transmitter connected to the serial port of my computer, and a RF receiver on the arduion board to collect the signal and perform some action.
Any ideas? Thansk!
I've seen some remote controlling using IR infrareds...but that has many downsides...
check on the arduino tutorials section in the playground

after you tutorial with the bluetooth antenna there is another wireless connection
through Zigbee...

but I have no clue on how much power demanding is that, ask the author eventually.
why is it too power demanding? what is your problem? the fact that you would like to run it on lower voltages? is it the bluetooth module that is power demanding?
please explain it better...I had in mind something similar to your project and thought that could be eventually ported, after prototype version working on Arduino, to a smaller and less power demanding processor... some atiny or the smd version of the Atmega8.
I'm not totally sure that that is possible though

hey sorry it took me so long to reply.
the blue tooth module is quite power demanding yet. it needs around 2 9V batterys in parallel to work.
i have read that arduino are making a bluetooth board, but this is very expensive.
you can use a module called "easy radio". its basicly a wireless serial port. its quite cheap, and very reliable since it buffers all the data, so you dont have any "packet loss"
