I don't have devices in mind. Accept all kind of suggestions.
The connection will be initated by the Arduino once he read the code. After this the connection will be opened until the button on the device is clicked. in this meatime, arduino will receive some commands in order to power on the lights and/or play sounds.
About physics, i plan do the same work as my laptop does with walls and wifi signal.
About budget, please, make me know your offer.
Thanks and regards
