How can I reset my arduino board using a gui button in matlab?

I am trying to look after a function to reset my arduino board, like acting the same way as the reset button, but using the gui button in MatLab.

Could anyone help me?

Hi Cristina,

I understand that you are looking for a way to reset the arduino board by using a GUI button in MATLAB. It is possible to do so using the Arduino support package for MATLAB.

To achieve the functionality of resetting an Arduino board programmatically from a MATLAB GUI, you would need to toggle one of the Arduino pins that is connected to the "Reset" pin. Although, this approach requires a physical connection between one of the Arduino's digital pins and its reset pin.

Here is an example function that will create a GUI button to resetting the Arduino:

function resetArduinoGUI()
    % Create a simple GUI
    fig = uifigure('Name', 'Arduino Reset', 'Position', [100, 100, 200, 100]);
    btn = uibutton(fig, 'Position', [50, 35, 100, 30], 'Text', 'Reset Arduino');
    
    % Specify the Arduino port and create an Arduino object
    arduinoPort = 'COM3'; % Change 'COM3' to your Arduino's port
    a = arduino(arduinoPort, 'Uno', 'Libraries', 'Servo');
    
    btn.ButtonPushedFcn = @(btn,event) resetArduino(a);
end

function resetArduino(a)
    % Pin connected to the Arduino's reset pin
    resetPin = 'D10';
    configurePin(a, resetPin, 'DigitalOutput');
    
    % Toggle the pin to reset the Arduino
    % Resetting is done by pulling the pin LOW, then back HIGH
    writeDigitalPin(a, resetPin, 0);
    pause(0.1); % Short delay
    writeDigitalPin(a, resetPin, 1);
end

Note that, I am assuming that you are using Arduino Uno in this specific case.

This method should effectively reset your Arduino from a MATLAB GUI, mimicking the physical press of the reset button on the board.

Additionally, you can also look at the following references:
