    I can't think of what the exact pin connections were for the stepper drivers and I disassembled it a long time ago. There are dozens of good tutorials out there for the A4988 drivers that I followed that explain everything way better than I ever could so go check some of those out.
    I made this project with almost no background in electronics and using online forums and video tutorials for almost every component and the code. Learning by doing (and failing) is most of the fun for things like this. Good Luck : )

    The electromagnet worked for me because I was powering it with 9 Volts instead of 5. Also, the most important thing is to make the distance between the magnet and metal ball as small as possible. I used an acrylic sheet that was less than 2 mm thick and had the magnet almost touching the bottom side of it.

    I tried a bunch of different motor drivers but ended up using two A4988 drivers. I used cheap steppers that needed adjustable current limiting to work properly. I tried the L298N and L293D but they would get way too hot because there not rated for the Amp of current I needed for the steppers.
