  RELAY  Relay isbasically an electromagnetic switch which can be turn ON and OFF by applying the voltage across its contacts.  In this project we used a 12V 5 pin relay

  ADVANTAGES  It isa robust and easy to use system.  It will save your energy and money.  Provides Security.  Convenience and comfort.  Can be used by physically challenged and disabled people.  Complexity is less as only a single mobile is used multiple devices.  Smart home technology.
• 16.
  DISADVANTAGES Only works forlimited range or short distance with in 5-10m surroundings. No feedback path. Number of appliances which can be controlled through this circuit are limited. Circuit complexity increases as number of devices increase.
• 17.
  FUTURE WORK  Thissetup can further be developed into IOT project by using Ethernet arduino and a wifi module.  So , it can be controlled from anywhere around the globe having feedback from the devices to further improve the energy savings.
