We can't see your code (hint). And "not working" is a very poor description. After posting your code, please describe what it actually does and how it differs from your expectation.
Your topic has been moved to a more suitable location on the forum. Installation and Troubleshooting is not for problems with (nor for advice on) your project.
Please do not duplicate your questions as doing so wastes the time and effort of the volunteers trying to help you as they are then answering the same thing in different places.
Repeated duplicate posting could result in a temporary or permanent ban from the forum.

“It doesn’t work” is not a good description .
Here are the things that fall into that category:
It isn’t powered on (the led does not light up)
It gives an error when trying to load code to it
It has exploded and taken out half the block
It has revealed itself as a decepticon and is trying to take over the word
Etc ad infinitum
