From your post we don’t really get much information other than you’re a beginner and you want to make something (Please refer to the guidelines for this category for how to properly structure your post).
It would be helpful if you could tell us if you’ve tried creating one already or not. If you did and it didnt work or it’s broken, we can assist you in finding the issues and fixing them. If you need assistance with coming up with ideas for how to tackle it from scratch, please make that clear.
