I'm working on a project that I would like to use a raspberry pi computing system to control electromagnets with pulse width modulation but I'm hindered by the thought of the magnets causing too much interference with the computing system and I'm wondering if its possible to do such an experiment any thoughts as how to go about this and I should also say that I'm a little bit new to using the raspberry pi and I'm wondering if I could get a few helpful hints on how to do coding and other things.
