Hi,
Apologies if this is a trite question but this is my first dive into the hardware world. I need to separately control four electromagnets from a Raspberry Pi. The only ones I have found are the Grove electromagnets. However, I can’t find any info on connecting four at once using the Grove architecture. Is it possible? Or would I need to pair each magnet with a microcontroller and talk to the controller from the Pi? If so how do I best connect the controller and Pi together?
Many thanks
PJ
