I want to make IR SWITCH Circuit

[Umair Khalid]

Hello Friends, I want to make a IR Switch Circuit, to turn blub,light or fan by using a remote, Plz help me out in making this,
And plz post circuit diagram,
I want to turn on/off a 12V Fan using a remote
Plz show me the schematic diagram of the circuit,

There are many circuits that can work as you need.
You need an IR transmitter, a LED fed from a battery through a switch and a current-limiting resistor.
Then you need to tell us how far you need the range.
This can define the IR receiver complexity.

You can use a "remote" IR controller as the transmitter but then you need to know what frequency its IR light is modulated. You must design a receiver to respond to it.

There are many cheap commercial remote controlled switches, mostly using RF , some also IR.
Do you want to have the device, or try to design it?
