WARNING: Newbie here 
I'm trying to make a digital clock using ds3231 and 8x32 cascaded Led matrix. I am done setting up the DS3231 module but i cant seem to find a proper tutorial with using the led matrix. Can someone here help me out with the sketch and libraries?

Welcome to the Forum. Please read the two posts at the top of this Forum by Nick Gammon on guidelines for posting here, especially the use of code tags ("</>") when posting source code files. Also, before posting the code, use Ctrl-T in the IDE to reformat the code in a standard format, which makes it easier for us to read.
Can you please read Sticky Topic How to use this forum - please read.
http://forum.arduino.cc/index.php?topic=148996.0
Can you please post a copy of your sketch, using code tags?
They are made with the </> icon in the reply Menu.
See section 7 http://forum.arduino.cc/index.php/topic,148850.0.html
- Tips for getting the most out of your post
- Mention which Arduino you have. Is it a Uno? Leonardo? Due? Mini? Mega? The problem might be specific to a certain model.
- Describe your problem in detail.
- If it relates to an electronics part (chip or board), give the exact part number and preferably a link to the data sheet.
- Describe how you have connected things like switches. Are they wired to ground? Or +5V? Are there pull-up or pull-down resistors? Post a circuit if there is doubt.
- Post a complete sketch (program code)! If you don't you waste time while people ask you to do that. However, with coding problems, if possible post a "minimal" sketch that demonstrates the problem - not hundreds of lines of code. If the problem goes away in the minimal sketch, it wasn't where you thought it was.
- Copy and paste code. Don't retype "from memory" on your mobile phone, in the train.
- If you get an error, post the error (copy and paste). Not just "I got an error".
- If you have debugging information in your sketch, post your debugging displays.
- If you are using a library that does not come with the IDE (in other words, you downloaded it from somewhere) please post a link to this library.
- Describe what you expected to happen, and what actually happened. Not just "it doesn't work".
- If possible, describe what you are really trying to do, not what you think might work. For example "I am trying to turn on an aquarium heater and pump at the same time", not "how do I break out of an interrupt?".
- Try to narrow down the problem, whether coding or electronic. Don't confuse us and yourself by trying to do everything at once. For example, if you are having problems reading a sensor, make up a simple test case, that tests that sensor (both electrically and in code).
- Put your location (country) in your forum profile. That allows answers to better help you with mains voltages, local suppliers, and other local issues.
Not to mention section 13: Don't bump!
That said, here's some help: this project has been done before. Browse everybody's "favorite" website, Instructables.com for ideas about how to do this.
