This is an example of how you can use App Designer tool to build program to control any hardware over supported protocol (i.e. serial).
HOW TO GET
Execute in MATLAB:
App Designer has visual instrumentation components (knobs, swithes, etc.) so it allows you to build interactive apps for instrument control.
The submission contains a scheme of Arduino based simple device with RGB LED and photoelectric cell. Simulink program for Arduino is provided (requires Arduino Support Package).
With interactive program you can control the RGB LED color and observe illuminance level over the serial connection.
Instrument Control Toolbox is required for optional features.
Also there is a describing video (on Rissian, for old version):
* Please note that app versions for old releases aren't maintained and are presented just for legacy *

apple, it depends on your operation system settings. I have a green theme in my Win10.
Thank you Pavel, How to set the background color of the Title 'Instrument Control over Serial' to green?
Amirala Barjasteh, thank you!
You can see and edit main code in App Designer tool (R2016a and newer). Open 'rgb_control.mlapp' in App Designer (in MATLAB: Right click -> Open) and press 'Code View' button.
FYI: Introduction to App Designer (video)
Thank you Pavel! really interesting!
Is it possible to see the main code of this app? I mean you describe sth about code but I could not find any script in files.
You can create another Timer that will check if your serial port available and opened.
Check whether port is opened:
s = serial('COM6'); % COM6 for example
s.Status % 'opened' or 'closed'
Returns all available serial ports:
p = instrhwinfo('serial')
Thank you for shearing!!! do you know how can i change the the program that the LED would change its collier wean Serial is disconnected? and not only by Event?
can i run a loop that will check for communication all the time?
abd saleh, thank you for your interest. I have updated the discription and added an <App Designer Eng.pdf> file for better understanding
I want to explain more please
- Update RGB app, new LED app and model. Update docs
- App, model and documentation have been upgraded to R2017b
- finaly added model previews
- added model previews
- updated Simulink model for Arduino: Buffer block is rejected due to a new ability of Serial Recieve block to recieve an array of elements (R2017a)
- added version compatible with R2017a release
Update cover picture
- new graphics features (area plot)
Update the discription, add <App Designer Eng.pdf> with diagrams for better understanding.
