I don’t think so, but I’m not sure which light dimmer module you are talking about. I also don’t know which fan you are trying to control… Are you talking about a 12V DC fan?

light dimmer

No iam talking about ceiling fan(230v 50Hz)

If it’s an AC fan, yes you should be able to control it with that AC module. However, I’ve personally tried it, so unfortunately I don’t have any tutorials on that exact subject…

I’ve used that module in some personal projects before and it works perfectly to control AC lights.

by PWM technique,one can control speed right ?
can you please share some useful links for speed control of fan?

Exactly, that AC module should allow you to control the AC fan speed, but I can’t guarantee that module will work with your specif fan, because I’ve never tested it before…

Note: your AC fan must be single phase control.

I recommend going to the official AC light dimmer module page: robotdyn.com/ac-light-dimmer-module-1-channel-3-3v-5v-logic-ac-50-60hz-220v-110v.html

In their product page, they have some resources after the product image:

• DETAILS | REVIEWS | SPECIFICATIONS | TUTORIALS | DOCUMENTS | GIT

I recommend going to the specifications/Documents to learn more about the module.

Then, open the tutorial tab to learn how to wire the module. Then, you can go to their GitHub repository: github.com/RobotDynOfficial/RBDDimmer

That’s the official library for that module, it shows the pins that you need to use for each board and it has many examples.
