Help with video game controller using rotary encoder on the Arduino Leonardo

Thank you for the reply. I have very little knowledge about making electronics and coding. I need to do more research on the subject. I saw a video on Youtube about someone who made something like this and thought, "I can make that". I think I was too impulsive and hastefully bought the supplies I thought I would need for this project, not thinking how much I needed to learn to complete it. I have no more questions for now. I'm just going to do some more searching. The fun part of this project for me is the process of making it, not just using the finished product. I will post later if I have any more questions. Thank you again. I appreciate your help.
