Hello,
From my understanding, you are receiving an "Cannot detect arduino hardware" error when trying to connect an arduino in MATLAB on Macbook while using the "arduino()" command.
Without specifying parameters to the "arduino" command, MATLAB seems to be having trouble detecting Arduino devices on your machine.
Please try connecting to the Arduino board by explicitly specifying the port ID and board type in the "arduino" call. On a Mac the port string often starts with "/dev/". As an example:
>> a = arduino('/dev/tty.usbmodem1421','Uno')
a =
arduino with properties:
Port: 'COM3'
Board: 'Uno'
AvailablePins: {'D2-D13', 'A0-A5'}
Libraries: {'I2C'}
There could be several reasons you are experiencing the issues. You can try the following troubleshooting steps mentioned in the MathWorks documentation.
