Welcome to this simple page on adding two cell phones together to send two signals when your security system has been activated or what ever you like.
If you would like to see the two phones calling at the same time then I have uploaded this to my You Tube account.
1). On this simple page we will look at adding a second phone on the same network or a different network to send our signal if your security system has been activated this idea can be used with all my project on You Tube.
2). All you need to do is have two cell phones and twist the two wires together like in the photo below.
3). Now when you have twisted your wires together you will need to touch the wires together and see if the two phones activate at the same time, If not then reverse the wires and try again see photo below.
4). Now after you have twisted the wires together like in the photo above and found the two phones activate at the same time you can now connect the wires into your little green circuit like in the photo below or what ever you like.
5). Now as this is only the demonstration of the two phones calling at the same time I have just connected a PP3 battery clip and battery to activate the two phone this can be used for thousands of things.
6). You can see the two phones connected to my smoke alarm receiver in the photo below.
