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.
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
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?
