Why we need it…
Forgetting to switch off
devices while leaving
home.
Needs arising to operate
devices while we are not
able to access them
physically.
Devices are connected to
an embedded system.
The embedded system is
programmed to control the
devices according to
commands from a remote.
Implementation …

1. User sends commands via SMS
2. Mobile at the system transfers it to Micro controller
3. The Microcontroller operates the Devices according
to the command received.
