Arduino not functioning

Hello, I am currently using Linux Lite OS with Arduino IDE. I have no problems with uploading the code itself, it just doesn't work. The Arduino is not responding at it, but at the IDE it says the upload was successful. I'm not sure if the serial port is the problem.

More details, maybe?

My current arduino is this: https://www.dfrobot.com/product-345.html

Like I said before, there's no problem uploading the code to the Arduino itself, it just doesn't work (for example the project led I tried to do doesn't light up).

So, let me get this straight - the code that you haven't told us anything about, doesn't do something that you expect it to, and those expectations are also some kind of secret?

Did I sum up your situation correctly?

I used the sample code on dfrobot, you can actually see it if you click on the link that I gave.

And, no you didn't sum up my situation.
