are an alternative to
. They offer something that DC motors don't, reliability. Their movement can be closely tracked by
keeping count of how many times you step the motor. Each step is correlated to an angle of movement. The stepping angle depends on the motor but some are very precise,
this is probably why stepper motors were used in early computer disc drives.
One disadvantage to stepper motors is that they tend to suck alot of current from batteries. Stepper motors
tend to get really warm because of this, but that is just how they are.
The L298HN Stepper Motor Driver
The Stepper Motor
Purpose & Overview of this project
The purpose of this project is to control a standard 9.2v stepper motor using the L298
(L298HN) Stepper Motor Driver. This chip is designed to be able to control one (2-coil) stepper motor so it should be able
