Hello world! First post here. I’m looking for feedback/advice on a motor controller / current sensing system. I'd like to replace the existing fritzy controller, which opens six skylights via ~30V geared DC motors. I’d like to control mine with an Arduino (maybe someday it’ll be based on time of day, rain, etc). I’m hoping to fit this in the original 2-gang electrical box, so ideally the circuit is simple and small. I’m planning to design my first PCB (through-hole) to keep it compact. For motor drivers, I chose SN754410 half bridge drivers and they’re working well.
