ı have got a project.I want to circuit diagram and assembly code of controling motor.but i must to use ULN2003a chip on the circuit;
TOPIC=Multiple-Peed Stepper Motor Control and Digital Display

(To be submitted by 5 January 2006)


The term project is about writing an Assembly Language Program to control a Stepper Motor interfaced to a PC through the parallel port. The project contains the following 3 main modules:

1. Stepper Motor Driving Module (Output Module):

· The motor will rotate clockwise if f (forward) key is pressed and will rotate anticlockwise if r (reverse) key is pressed from the keyboard.

· The speed of the motor will be controlled by the external push buttons (Up and Down) connected to the PC through the parallel port. If Up button is pressed the speed will be incremented by 1 out of 10 speeds. Down button will work similarly.

2. Speed Display Module (Output Module):

· The speed of rotating motor will be indicated by displaying a single digit 7-segment display. There will be speeds from 0 to 9. The speed which is displayed on the 7-segment display will also be displayed on the monitor with its direction (clockwise or anticlockwise)

3. Up and Down Push Buttons (Input Module):

· The speed of the motor will be controlled by the two external push buttons. The speed will be incremented or decremented one by one by pushing to Up or Down buttons respectively.Confused | :confused:
