If you want to learn the basics of l293d ic below tutorial is invaluable.
Stepper motor controller ic.
These include control of step size number of steps per single command number of actions from 1 to 255 or continuous rotations and direction of rotation.
The position of the knob determines the position of the motor shaft which w.
Very low acoustical noise.

This instructable will show you how to control stepper motors unipolar or bipolar manually with a knob without the use of a pic or pc so no programming is needed.
They combine in a single chip all that is needed to autonomously drive a stepper motor using high level motion commands coming from the motor or motion control system host a microcontroller dsp or fpga.
Generic ics for stepper control.
Drive unipolar stepper motors as bipolar stepper motors with a simple wiring reconfiguration.
E523 39 is a high precision automotive bipolar stepper motor driver for up to tjunc 170 c and phase currents up to 1 2a with spi interface and 10μa sleep current.
This ic contains seven darlington transistors that each include diode protection and are capable of providing a 500ma 50v output which is actually more than the arduino uno can handle.
You don t need an ic that is specifically labeled or marketed as a stepper control device.
During the operation of a stepper motor characteristic current and voltage profiles occur with each succeeding step allowing a conclusion about the.
It can control both speed and spinning direction of any unipolar stepper motor like 28byj 48 or bipolar stepper motor like nema 17.
The first thing to keep in mind is that ics intended for basic motor control functionality or even just basic driver functionality can be used with stepper motors.
Simple manual control of stepper motors without a pic or pc.
