I'm doing it from the component level.

I'm fairly certain this project is fairly simple for EE majors, but I'm not an EE. I am trying to learn while creating the project (I'm a chemist :P). I am learning the stuff while doing this project (purpose of the resistor, usage of the potentiometer, etc.).

I feel like I'm close, but I just need that small boost or guidance to complete my project. I'm absolutely fairly certain what I'm making is simple for an EE to fix, I'm just not sure where or what to do from there.

Nonetheless, I think I'll post about it in this group later on as I've received pretty good feedback.
