An H-bridge is an electronic circuit that switches the polarity of a voltage applied to a load. These circuits are often used in robotics and other applications to allow DC motors to run forwards or b

A stepper motor, also known as step motor or stepping motor, is a brushless DC electric motor that rotates in a series of small and discrete angular steps. Stepper motors can be set to any given step
H-bridge
…push–pull converter, isolated DC-to-DC converter most motor controllers, and many other kinds of power electronics use H-bridges. In particular, a bipolar stepper motor is almost always driven by a motor controller containing two H-bridges. H-bridges are available as integrated circuits, or can be built from discrete…
A stepper motor
The 28BYJ-48, accompanied by a ULN2003 driver, is one of the most popular stepper motors among hobbyists.
Stepper motors like this are often accompanied by a reduction gear mechanism to increase the output torque. The one shown here was used in a flatbed scanner.
