I'm considering starting a new RPI project that will end up being a haptic feedback suit for video games. My thought process so far is that I can embed a lot of piezo crystals inside a vest / jacket of some sort, and control those from a Raspberry Pi. The only problem is that I'm not super great with interfacing a Pi with hardware devices (motors, speakers, etc.)
I'd assume I'll need something to sit between the Pi and the piezos, to provide an AC current, enough power, and probably protect the Pi from any electrical currents coming back from the crystals.
Is there some sort of hat or other device I could use for this purpose? Thanks in advance!
