But what did you get so far? The question (as I read it):“what do I need to do to make my project?” is a bit of a vague question, not to mention the fact that we aren’t supposed to make your project 
If you need help with specific things, then please ask specific questions. “I looked, but haven’t found, what to do?” is not something we can answer here.
Looking at the code (which @ScruffR rightfully dubbed as questionable), it seems there are some things off. Disregarding the fact that you seem to lack a couple of brackets (if cases) that would cause issues, it seems as though you’re using the Servo object even though it was mentioned that that wouldn’t work.
I’m with @ScruffR on this one, Hackster is generally meant to share complete projects, it’s not a troubleshooting site, and really shouldn’t be used as such. If you want to share code and/or get improvements on it, then please place it on Github, or directly on the forums here. Then we can help out, and when you’ve got it working, you can post it on Hackster.
