use a a to d converter to send and a d to a converter to recive.
if you do that you can just apply voltage to the sender and to fan/light will change speed or brightness
sorry, lol run a infered led from a A - D converter.
use a infered phototransistor to a D - A converter to run a amplifyer to the fan.
i don't know how a d-a conveter works and i don't know how a a-d converter works.
Sorry 'danielsmusic', but your suggestion makes no sense at all!.
The project really consists of two parts, one is the IR control, the second is the actual control of the two completely different items. An incandescent lamp can be controlled by phase shift power control, a fan depends entirely on the particular type of fan!.
im looking for a circuit with a microcontroller which will be using pwm for speed and intensity control. plz can anyone tell me how to do it. or if anyone can get me a link that has all this

Light Intensity of AC bulbs can be easily done by varying the firing angle of a TRIAC (antiparallel SCRs). You need to connect the AC bulb in series with the TRIAC. Also required is a DIAC which will be used as a firing device. There is no special requirement of a microcontroller here.
