im sorry--
im planning on setting up a second switch in the garage. But how will it be possible to use both switches in the garage? ---They needed to be tree way switches.. as jimmy said.
But unfortunet the switch who is in garage now is only one pole.?
will it be possible to use arduino to sort out this problem.? or should i buy tree way switches insted.
Future implanning on setting up a door switch. - Like when u enter, the lights will turn on. Here i will be needed to use relays, but why buy tree way switches when i can just buy one new one pole.?
