I need help for a school project
I'm trying to drive two bipolar stepper motors using two DRV8833 double h-bridge and an atmega328p mcu (with arduino bootloader)
Unfortunatly, I am restricted to using two AA batteries,
The stepper motors actually draw 1Amp per phase, so it does a lot of noise and my mcu keeps reseting, even with a regulated source
I actually have no problems driving the motors with the batteries as long as the mcu has a seperate source
I was looking for a way to have a clean voltage for my mcu, perhaps some kind of isolator thath would act as an impedance to the batteries and generate a new regulated source for the mcu
i also thought about using the 2 batteries as two seperate sources along with step-ups, but i doubt drawing up to 3-4 amps from a single AA batterie would work
