I expect there is a problem with the way you have things connected up, the way you're trying to drive the dimmer or with your code in general. I can't see any of those things so it is just a guess.

Also, please give us links to the information/specs for the mysterious "dimmer module".
We'll also probably need to see your code.
And, I assume you are using a regular incandescent light bulb?
Just like you, we are in the dark.
We need more information from you to be able to help you solve the problem.
