END MAIN (This is the code that I currently have, this code currently changes the speed from the keyboard and changes the rotation direction from the mouse. I just want it the other way around were I change the rotation direction from the keyboard, and changing the speed of the motor using left and right click) We are using ULN2003A stepper 5V motor Seven segment display IC 7447

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: The motor will rotate clockwise iff (forward) key is pressed and will rotate anticlockwise ifr (reverse) key is pressed from the keyboard. The speed of the motor will be controlled by the mouse. If the left button is pressed ("clicked") the speed will be incremented by 1 and If the right button is pressed ("clicked") the speed will be decremented by 1. 2. Display Module: The speed level (from speed 0 to speed 7) will be displayed on the monitor and the 7-Segment Display connected to the Parallel Port. i) You can do the project either alone or within a group of 2 students. ii) A report must be submitted for each project. Each group will demonstrate their project in the lab.
