SMS Remote Control

With this circuit we can controll up to 8 devices (4 devices in our example project), by sending a specific SMS message with any mobile phone. Its very usefull at the cases that, at the place we have the devices, we have not a wired telephone line. If you have an old ericsson mobile phone and you are not using it, its the time to build some useful with that.  The controlling that we can do to the devices, it is ON , OFF or Reset.
