You mean, like this?Hello all! I'm in a college class where I have to make a project using a RP2040, and I think I want to make an electromagnet that you can turn on and off. Would this be a super difficult project for a complete beginner? I know I would need an external power source, an actual magnet (I'll be making it by wrapping copper around an iron nail), a diode, and a MOSFET (although I'm not sure what that actually is). I think I would also need a breadboard, which I also haven't had experience withAny advice you could give would be greatly appreciated!
