Connect to Arduino Hardware

This example shows how to connect to Arduino^® or ESP32 hardware in MATLAB^®.

Make sure the Arduino or ESP32 hardware is connected to the computer. If the device is unofficial, note the port and the board name.

Connect to an official Arduino hardware.

Note

Arduino Due boards support only the Programming port for communication.

a = arduino()

a = 

  arduino with properties:

                    Port: 'COM4'
                   Board: 'Uno'
           AvailablePins: {'D2-D13', 'A0-A5'}
    AvailableDigitalPins: {'D2-D13', 'A0-A5'}
        AvailablePWMPins: {'D3','D5-D6', 'D9-D11'}
     AvailableAnalogPins: {'A0-A5'}
      AvailableI2CBusIDs: [0]   
               Libraries: {'I2C','RotaryEncoder','SPI','Servo','ShiftRegister','Ultrasonic'}

Connect by specifying the port and board name.

If you are using an unofficial (clone) Arduino hardware, specify port and board name to establish connection.

a = arduino('COM4','Uno')

a = 

  arduino with properties:

                    Port: 'COM4'
                   Board: 'Uno'
           AvailablePins: {'D2-D13', 'A0-A5'}
    AvailableDigitalPins: {'D2-D13', 'A0-A5'}
        AvailablePWMPins: {'D3','D5-D6', 'D9-D11'}
     AvailableAnalogPins: {'A0-A5'}
      AvailableI2CBusIDs: [0]   
               Libraries: {'I2C','RotaryEncoder','SPI','Servo','ShiftRegister','Ultrasonic'}
