Connecting multiple electromagnets


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

Hi nickwa,
welcome aboard… I would take a look at the wiki it’s got many options.
Depending on the current draw, four Grove connected ports are available. (D3), (D2), etc.
