Have you ever wanted to remotely turn on or off something in your house when you weren’t home? This time of year the Christmas lights come to mind. What if you could call your house, type a few keys on your phone and turn on those lights! With this Phone Line Relay Controller project that is exactly what you can do.
"The administrator should call-in the device from another telephone. After a few (configurable amount of) rings, the controller will pick-up the line and answer with a beep. After the beep the administrator must enter 4-digit password onto the keypad of his phone (DTMF). This must be done in 6 seconds. If the password is not entered in 6 seconds or wrong password has been entered, the device will beep and hang up."
