parallel_dev
{
struct cdev cdev;
};

1. Parallel port 25 pin male connector.
2. Stepper motor.
3. ULN 2003 IC.
4. 24V power supply.

we our case we used permanant magnet type unipolar stepper motor with step angle of 7.5.
and IC ULN 2003 is used to drive motor because output voltage and current available from PC(parallel port) is not sufficient to drive motor…
read ULN 2003 datasheet and Basic working of stepper motor before starting to work on actual hardware….

What output we will send to parallel port for running stepper motor and what are hardware requirements for implementing the stepper motor project??????
