This is a very cool electronic project to control dc loads using a very cheap and reliable design. This video also explains ...

The controller in question is a 4QD Porter 10 so an extra component is a DC-to-DC converter to provide a floating ground for the Arduino.

Core-less brushed DC motors have low inertia and inductance. This lets them be used in applications needing dynamic behavior and fast responses from the motor. Using PWM allows precise current ...
