i have just joined the group...
i'm very much interested in electronics field...

i want to make an electronic device(remote controller) that contols the speed of ceiling fan.
so plz give me guidelines for this...
tell me what mechanism can be used for this?
 
sunilthorat, what books have you studied? What kind of knowledge do you have about electronics already?
 
remote contol!

It's possible using HOLTEK HT12A/B IR encoder/decoder chips. Gives 4 channel output for four different speeds.

Hi SC, HOLTEK IC's are used commonly in commercial appliances for a variety of applications that requires n-channel remote controlled operations.This doesn't seem to be a simple project for an electronics newbie but surely a good learning project, sunilthorat. Try it! It uses HT12E/D pair.

You should choose the light dimmer output for controlling the fan. Other one is used for inductive loads such as fluorescent lamps.
