hi guys and girls
so im having a project to opening a garage door with a phone call why the phone call because i dont have wifi in the propety .
im from portugal , and my idea is to have a board that carries a phone card with x number (this board should work as a relay) so when i call the x number the relay closes a circuit and opens the garage door .
i will apreciate your guys help thanks a lot in advance
