Conclusion

In this project we created a graphical user interface

for controlling the output of Arduino in the Matlab

environment by synchronizing the Arduino output to

work according to pushbuttons created in Matlab Gui

tool .

In the following slides we will tell about the

graphical user interface and the Arduino and

serial communication of Arduino with laptop

and then synchronising of Matlab with Arduino.

Graphical User Interface (GUI) MatLab provides Graphical User

Interface Development Environment(GUIDE).

A MatLab tool is used to create GUI’s GUI’s give the user a simplified

experience running a program.

6

GUI should be consistent and easily understood.

Provide the user with the ability to use a program without having to worry about commands to run the actual program

Possible components of a GUI

Pushbuttons

Sliders

List boxes

Menus….etc

Sample GUI

7

Allows the user to drag and drop components that he/she wants in the “layout” area of the GUI

All “guide” GUI’s start with an opening function

Callback is performed before user has access to GUI

Saving automatically generates an .m file and .fig file

.fig contains the binary GUI layout and .m contains the code that controls the GUI

Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing / Wiring language. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer.

Analog INPUTS

Digital I\OPWM(3, 5, 6, 9, 10, 11)

PWR IN USB (to Computer)

SCL\SDA(I2C Bus)

POWER 5V / 3.3V / GND

RESET

Also including an Integrated Development Environment (IDE) for programming.

The language itself is based in C .

It is Open Source, both in terms of Hardware and Software.

It is cheap(1300रु), the hardware can be built from components or a prefab board can be purchased for approx 900रु.

It can communicate with a computer via serial connection over USB.

It can be powered from USB or standalone DC power.

Plug it into the USB port and install the USB drivers that come with the IDE.

Open up the Arduino IDE and select the COM port, usually COM1 or COM2 on a Windows machine.

Within the IDE, select the BAUD rate (communication speed for serial connections)

Set BAUD rate to 9600 on Windows.

There is arduinosupport package which works with Matlab.

Code is written aside so that arduinooutput is controlled via using matlab.

.

clear all;

global a;

a= arduino(‘com 1’);

a=pinMode(4,’output’);

a=pinMode(8,’output’);

the name of push buttons can be changed by changing string name.

In simple control of two leds , two pushbuttons are being created in the gui tool then the codes to be written to control the output of arduinothrough pushbutton is given as

For pushbutton 1

a=digitalwrite(4,0);

a=digitalwrite(8,1);

For pushbutton 2

a=digitalwrite(4,1);

a=digitalwrite(8,0);

In this project we have demonstrated to link the Matlab to control arduino output.

Here only pushbuttons are to be used by the user so no need to write the program again and again once the decalartion has been done .

This project doesn’t need exceptional coding skills for arduino and matlab . A simple knowledege to both can work .

Now this can be extended for home automation

using gsm module/bluetooth/android

application/ dtmf .

For eg if we use gsm module we can connect

with arduino via transmitter and receiver pins

then programming the gsm module using AT

commands and we can control the basic home

appliances just by dialing the phone no

associated with the gsm module .

1. Serial port communication : the arduino used was not working because of the serial port was not getting identified in the computer.

2. Gsm Module : while working with gsmmodule the supplied voltage of 12V was given instead of 9V which led to the damage of it and it doesn’t catches the signal .Overall we couldn’t extend our project because of this anamaly.

Project is useful for the purpose of home

automation if extended further and is reliable

once installed . Our project dealt with simple

implementation of connecting matlab and

arduino to control the variables or equipments

connected on the output pins of it.
