This is a nice tutorial thanks a lot Dejan. But one important comment for people who have ther MAtlab 2016 version please be aware that function codes like set a digital pin or write a digitial pin has been changed: digitalWrite will be writeDigitalPin(a, 'D13',1) Like this there are more difference check the help funciton in Matlab and the examples to find out!
Do you know how to do a waveform for speech recognition? Like I have an app and it is connected to arduino to control leds. Then, I need to show a waveform.
Nice one Dejan! I just have a question!! Would you please tell me what is this value that you were entering in the read box like 500 or 1000!???? And what are the quantities that you are plotting like what is along the Y-axis and what is along X-axis???? Please answer me.
matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)sample1('turn_on_button_Callback',hObject,eventdata,guidata(hObject)) Error while evaluating UIControl Callback i got these error. can you tell me what is the problem?
I have the same error like #Abdou Abdou, can you help me? "Struct contents reference from a non-struct array object.

Good day sir. What would be the Arduino code for this? Maybe your code might help me doing my project. I used MATLAB GUI for my microcontroller I always encounter error. I have an Arduino program for sensors, servo motor and LED uploaded to my microcontroller and they work well. I see values and status with the Arduino software's serial monitor. MATLAB's GUI is what I need to make it user friendly, so that anyone can easily monitor and control the devices to my project. Can you help me with this? Or can you make a video where you can see the values printed with Arduino's serial monitor with MATLAB? Thanks.
Oh, great work. May you live a long life Full of gladness and health . May all God's blessings descend upon you. May peace be within you. May your heart be strong. May you find what you're seeking wherever you roam.
I know know how to make a apps by matlab apps designer which is much better than matlab gui by GUIDE. but I don't know how to add it with hardware. Please could you help me?
Hello ,firstly thanks alot for the video it really helped me. Secondly could you tell me how can i update the plot continously? I mean when you press READ and as long as you dont close the port i want the data to refresh itself in time. Thanks anticipated.

Thank you Dejan, very useful and helpful. Like to ask and a bit confused. Did you run arduino sketch first and then communicate with matlab for this particular project?, If my understanding correct after seeing you Tutorial 7, you need to run arduino sketch first and the use Matlab to communicate via serial port. Meaning that you control you arduino using arduino IDE and matlab for getting the data out. Please correct me if I am wrong.
Hello. Greetings from Brazil. Great video, but due to not understanding much English, I was left with a doubt. I can use all libraries available for Arduino. Thank you
It's a great lesson, but I'm having a problem with an error in gui_mainfcn (line 220) and Error in Example1 (line 42), do you know something about it? I would realy apreciate the help, thanks.

Hi buddy.I didn't get it.Why were there "data1" and "xSamples" at 10:32 ? What do they mean ? Can I use "data" or "data2" or something like those instead ? And I have a small question that is not much relevent to your video.Do I have to programme all over again in Matlab environment instead of just uploading my code into Arduino via Arduino IDE (in case I have a new code) and then all I have to do is just the GUI to make it work ? Is there any way to do it ? By the way,I did exactly what you did,but only buttons for LED worked,button "READ" and text didn't.When I tried to run button "READ",he command window showed me this stuff: "???

***** Thanks again.Apparently,I didn't notice that you attached the balloon that denotes your typo.After I've rewritten my code,it works now.Oh I think I can answer myself for the second question that whenever we want to run Arduino with Matlab,all we have to do first is upload one of the sketches supported by Matwork for Arduino into Arduino.Of course,the sketch chosen must be appropriate to our project.Do I explain correctly ? Amd counld you make a video about how to use Arduino libraries in Matlab or guide me about this one?.For instance,I want to plot results that I get from a ultrasonic sensor using Newping library.But I didn't know what to do at first.Thanks you very much.
It seems that version of the Matlab and the arduino's new plugins could be the problem. I got this 2 errors in my MATLAB 2016: Error in gui_mainfcn (line 220) feval(gui_State.gui_OpeningFcn, gui_hFigure, [], guidata(gui_hFigure), varargin{:}); Error in guitest_pr2 (line 42) gui_mainfcn(gui_State, varargin{:}); So this video needs at least an actualization.

Great video Dejan, but I found some errors in the code you show on the video, I have fixed some of them on mine, but there are some I can not do it, for example I can't show the plot in real time. If you have the fixed code you use in the test, could you upload it?. Thank you, you are doing a great job!
Dejan, Great video. I hate to say this but but just so you know the .IDE files dont really work with the newer versions of MATLAB, i.e. 2014a and on. Again, thanks for the very clear videos.
why turn on/off buttons work in the same time as the plot function is executing . I mean the callback functions in gui cannot execute simultaneously. it is the pause command which is doing some magic ?
so if I used ""ECG/EKG Arduino shield "" instead a photocell with the some code , can I get the signal perfectly ? ,if no how can I do it ? thank's a lot

Maarten Wijnants Great! I finally had the code working. But if you could please tell me what is the diference between GRIP ON and GRID ON!!! Thanks a lot again
The difference is more simple than it sounds. 'grip' is not a matlab function, and 'grid' is. this was a typo in the script. That's why Matlab gives you the error that it doesn't recognize the function grip. Enjoy your GUI!
Thank you for the helpful Video you have put on the TH-cam , I have a question about, how can I Connect my Heartbeat sensors (( which is On the Olimex ECG/EMG shield and arduino Uno)) TO the MATLAB software and see the sinusoidal signal Online ?

Dear Sir,
how to Pot 2 channel ADC on Axis Plot? Need help please sir
why turn on/off buttons work in the same time as the plot function is executing . I mean the callback functions in gui cannot execute simultaneously. it is the pause command which is doing some magic ?
+mohamed sellahi The callback functions can actually execute simultaneously however I'm not sure if this is just a time slicing approach.
dude arduino commands is different in matlab how did u manage to use them , for example the pinMode , or Digital Write or analog write
he uses the arduino IO support package for MatLab. Requires License to use it and original arduino boards.
so if I used ""ECG/EKG Arduino shield "" instead a photocell with the some code , can I get the signal perfectly ? ,if no how can I do it ?
thank's a lot

reply me if he works
No it does not work successfully
thank you.
Does this work just with Arduino MEGA?
I love your tutorials. I would like you to ask if you can make a simple desktop application to control a device.
how can one connect BCILAB ouTput from MATLAB.TO CONTROL SERVOMOTOR from arduino?
how can we interface bcilab and arduino,plz suggest ?
Thank you for the video, Is it work with Arduino Uno ?
+Dejan Nedelkovski OK, I try to use it with Arduino Mega like you but I see this errors (I change the pin 8 by 13):
No appropriate method, property, or field pinMode for class arduino.
Error in Example1>Example1_OpeningFcn (line 67)
a.pinMode(13, 'output');
Error in gui_mainfcn (line 220)
feval(gui_State.gui_OpeningFcn, gui_hFigure, [], guidata(gui_hFigure), varargin{:});
Error in Example1 (line 42)
gui_mainfcn(gui_State, varargin{:});
+Abdou Abdou perhaps you have to see another video Arduino Tutorial #07
will it work for ardunio uno...
Thanks so much!, Its very usefull your information
Dear sir,
Can i get the code (coding)?
It didn't work:
No appropriate method, property, or field 'pinMode' for class 'arduino'.
Error in Example1_Example1_OpeningFcn (line 67)
a.pinMode(8, 'output');
i have the same problem i think they have updated the package
@Felipe Boscardin
'pinMode' replace with 'configurePin'
Hi. Can I do the same with an Arduino Uno? TY
Yes, you can use Arduino Uno.
Doesnt work on 2015a.
starting from error :
Error in Example1 (line 40)

***** I only need the graph I have no LED
( Hi Dejan ,thank you for the TUTORIAL it works perfectly but I need to receive 1000 point per second(frequency
so please if you know the matlab's code tell me
Thanks again
how if with using 2 sensor PIR?
how to call data from simulink to Gui ?
can I apply ac to arduino if not than why
My Program name is : untitled1
Why when i put the "run" button, this lines appear :
" Error in untitled1 (line 42)
gui_mainfcn(gui_State, varargin{:}); "
Anyone can show me the way to fix this error
And this :
Error using untitled1_untitled1_OpeningFcn (line 65)
Failed to open serial port COM3 to communicate with board Uno. Make sure
there is no other MATLAB arduino object for this board. For troubleshooting,
see Arduino Hardware Troubleshooting.
Mr Kitter are you solved this problem ?
Good job sir..💛💛
Excellent. Maybe, could you help me with a track for a project.
I need to do a controller for a helicopter and I do not know how to do a virtual simulation with the transfer function of system and the function of controller.
Thank you for your time.

Do not make people lose their time... You should update it or take off the video. It doesn't work anymore.

@@manupatel1063 Hello, a have the same problem when I use the "analogRead(0)" command from the guide, I don't know how to use the code that you shared, can you explain me? please
Hi Dejan!
Really cool video was that. But i have an enquiry to make.
I did exactly the same as you did in this video, but whenever i successfully upload the code, it shows the following errors. The graph kills it always. Although the LED is still in work. Please help me! Here are the following errors shown to me-
>> gui_no_1

"I have done EXACTLY thee same like you."
Himanshu Sharma You should change 'grip on' into 'grid on'. Than your code should run fine
Let me give it a try !
It shows the grid lines (dotted lines) and the graph is changing values as per my read samples box too but no values plotting still!
Maarten Wijnants Great!
I finally had the code working.
But if you could please tell me what is the diference between GRIP ON and GRID ON!!!
Thanks a lot again
The difference is more simple than it sounds. 'grip' is not a matlab function, and 'grid' is. this was a typo in the script. That's why Matlab gives you the error that it doesn't recognize the function grip.
Enjoy your GUI!

+Ehsan Rashed Have you figured out how to read in a heart rate signal?
grate effort
Thank you bro
