 Bigger Bigger  Smaller Smaller  Reset Reset

Hello all,
I was wondering if it is possible to have an android phone send a command to arduino over bluetooth which than triggers a pulse to open/shut a valve for the duration of the button-press (on the phone). I want to use this to turn on multiple lights. The Arduino should work as a relais for the main power (if im correct).
I checked the web and I think it should be possible using the ADK board and a Bluetooth shield. What would be the best way to do it and what bluetooth component would be the best. 10 m is more than enough range for me..
To clarify my idea I made a visio drawing.
Here's the drawing

I found this bluetooth module online, is it ok for what I want? It does work with Arduino according to the comments:

Thanks for any help!! I really appreciate it!

Yes, it is. If you program the android appropriately.

Lights controlled by a valve?

Well, you know the web is always right. In this case, it really is.

Thanks for your reply but I still don't know what the best way is to do something like this. Is my scheme correct or do I need other components like resistors?

If you're asking how you would go about switching loads with your Arduino, I suggest you go to the area of the forum which covers that side of things. It's a frequently asked question and it would be a waste of time trying to answer it again here.

Why the arduino adk? An uno could do this easily, and you can get a simple bluetooth serial app and send commands from the android, much easier than writing an app
