It is always good to operate an electrical appliance with a remote control .It will be very useful to old aged people to have all the controls in a single remote (wouldn't it?)
And it would cut the costs required for switch boards at least.
Apparatus required :
1.IR sensor TSOP1738
2.Resistors -330k(2),I K ,220k
3.Transistor -BC 548,558
4.Capacitor -100 uf (16V),0.1uf
5.IC 4017
6.LED- red and green
7.Relay switch -5V
8.Battery (5V) /Adapter with a DC jack
9.Remote (TV /DVD)
10.Bulb (230V) and some connecting wires
Procedure :
1.Make connections as per the circuit diagram:

2.The remote control module is readily available in the market .We tried it with one like that but instead ,breadboard connections would do fine with the above mentioned components .
3.Special thing is about the relay switch it has Normally open and normally closed terminals which gets closed due to magnetism when supply is switched ON via DC jack to the remote controlled module.
4.Now connect the bulb to the module (bulb should be connected to supply of 230 V)
Use an extension box to provide supply to the bulb .
5.Now make use of your TV /DVD remote to switch ON the bulb !!
(The IR sensor in the module can accept frequencies of the range of TV/DVD remote control)
