This project involves designing a GUI in MATLAB to control a DC motor and LEDs using a parallel port. The GUI allows the user to turn on and off the motor and LEDs by clicking buttons that correspond to ports connected to each device. The MATLAB code includes functions for the GUI interface and callbacks that get the button values, convert them to a decimal output, and send that value to the parallel port to control the devices. The project aims to demonstrate skills in MATLAB programming and understanding how to interface hardware using a parallel port.

PREFACE This project is a comprehensive study of the MATLAB, a programming language. It tells us the use and commands of MATLAB. This project is intended to use in engineering and computer science. This project utilizes electronic concepts that can be helpful in understanding the electronic principles and the use of MATLAB. This project deals with the various number circuits and used in electronic systems. This project provides a very deep understanding of MATLAB software with standard circuit designing. ACKNOWLEDGEMENT I would like to express my gratitude to all those who gave me the possibility to complete this project. I want to thank my course instructor Mr. Mohazzab Jawaid for giving me permission to work on this project. Furthermore thanks to my engineering lab staff that gave and confirmed this permission and encouraged me to go ahead with my project. I am bound to the Honorable director of engineering for giving me such opportunity to work with our capabilities freely. I am deeply indebted to Mr. Mohazzab Jawaid whose help, stimulating suggestions and encouragement helped me in all the time of making this project. My friends from the Department of engineering supported me in my project. I want to thank them for all their help, support, interest and valuable hints. Especially I am obliged to my seniors. I also want to thank to our lab in charge for all his assistance on the ministerial computer. Our teachers was of great help in difficult times I will like to thanks each and every person, who helped and supported me and gave time to this project. 2

1. Objective & Purpose: Objective: To design an application in order to control the DC motor and LEDs using GUI based MATLAB program through Parallel Port. Purpose: To understand and be familiar of the commands of MATLAB software and the need and importance of this software in industry. 2. Description: A small description of this project is that we would be interfacing the dc motor and some LEDs through parallel port using MATLAB software. Most of the coding will be done through MATLAB. We will turn on and off the dc motor & LEDs. Some information about the ports and components that I am using in this software is given below; DC Motor: A DC motor is an electric motor that runs on direct current (DC) electricity. DC motors are fairly simple to understand. They are also simple to make and only require a battery or dc supply to make them run. Parallel Port Interfacing: Parallel port is a simple and inexpensive tool for building computer controlled devices and projects. The simplicity and ease of programming makes parallel port popular in electronics hobbyist world. The parallel port is often used in Computer controlled robots, Atmel/PIC programmers, home automation etc. It takes 5 volts. It can send a large amount of data at a time but when we talk about the larger distances we have to look at the serial port. This is actually the drawback of parallel port that we cannot use it for large data transmission, but wirelessly we can do it. . 4
Figure 1- Parallel Port Figure 3- data transmission 3. Working: I have made a GUI based project. How it works is that it actually takes the input from the user and on and offs the DC motor and 3 LEDs. I am going to use four ports; port 1, port 2, port 3, port 4 and port 5 for that. It is actually a series circuit. Port 2 is for DC motor and Port 3, 4 and 5 are for LEDs. Step one of this project was to design a GUI for this project and then the second step was to interface that GUI with my hardware. 5

5. GUI of the project: Figure 3- GUI Conclusion I can conclude that this project can be used for various purposes like for the interfacing of many other things like home appliances, Industries etc. This project helped me a lot in improving my typing skills and also my understanding the need MATLAB in market.
