What causes Arduino to reset?
An Arduino will reset when the usb port is reinitialized (read: usb cable replugged), and that could be due to the host computer sleeping, rebooting, or something else such as the whole usb controller restarting because another usb device was plugged in.
Why do I need an Arduino motor driver?
So mainly, any motor usually needs a driver circuit because its voltage/current requirements are different from the device that’s trying to control it. At a high level, a motor driver takes a “logic-level” input (desired “effort”) and delivers a corresponding “high-side” output to the motor.
Is Arduino a motor driver?
The Arduino Motor Shield is based on the L298 (datasheet), which is a dual full-bridge driver designed to drive inductive loads such as relays, solenoids, DC and stepping motors. It lets you drive two DC motors with your Arduino board, controlling the speed and direction of each one independently.
Do I need a driver for each stepper motor?
Since a micro-controller has it’s operating voltage limit, say 3.3V or 5V and many stepper motors works at higher voltages than that, then you need a driver to control switching of stepper motor voltages, this should not be done by micro-controller itself, otherwise you’ll end up “frying” the controller.
What is the need for a motor driver?
Motor drivers acts as an interface between the motors and the control circuits. Motor require high amount of current whereas the controller circuit works on low current signals. So the function of motor drivers is to take a low-current control signal and then turn it into a higher-current signal that can drive a motor.

Does a stepper motor need a controller?
Driving a stepper motor is a bit more complicated than driving a regular brushed DC motor. Stepper motors require a stepper controller to energize the phases in a timely sequence to make the motor turn.
