Hey Ahmad,

I understand that you want to know how to send data from MATLAB GUI to arduino IDE.

You can follow these general steps:

1. Create a GUI in MATLAB: You can create a GUI in MATLAB using the App Designer. Design your GUI to include input fields or controls where you can enter data.
2. Install MATLAB Support for Arduino: If you haven't already, you'll need to install the MATLAB Support Package for Arduino. You can do this by going to the "Add-Ons" menu in MATLAB and searching for "Arduino." Follow the installation instructions.
3. Connect Your Arduino: Ensure that your Arduino is connected to your computer via USB and that you have the Arduino IDE installed.
4. Write Arduino Sketch: In the Arduino IDE, write an Arduino sketch (program) that can receive data from MATLAB through the serial port.
5. MATLAB Code: In your MATLAB GUI, write code to send data to the Arduino through the serial port. Use the serial function to open a connection to the Arduino and fwrite or fprintf to send data.
6. Run Your MATLAB GUI: Run your MATLAB GUI, enter data, and use buttons or controls to trigger data transmission to the Arduino.
7. Upload Arduino Sketch: Upload the Arduino sketch to your Arduino board using the Arduino IDE.
8. Test and Debug: Monitor the Arduino Serial Monitor in the Arduino IDE to check if it's receiving data from MATLAB. Make sure the baud rates in MATLAB and the Arduino sketch match.

I hope this helps!
