i'm using matlab 2020a. i've followed every instruction on
but somehow everytime i run
a = arduino('COM3', 'Uno', 'Libraries', 'Adafruit/DHT22');
i got an error
"Cannot program board Uno (COM3). Please make sure the board is supported and the port and board type are correct. For more information, see Arduino Hardware Troubleshooting."
i tried to run listArduinoLibraries and the name of the libraries is there
is there anything that i can do with this?

Hi Muhammad Hilmi Al Farid Ni'man,
Can you please confirm if you have copied the Arduino library folders namely Adafruit_Sensor and DHT to the libraries folder whose path is given by
>> fullfile(arduinoio.IDERoot, 'portable', 'sketchbook', 'libraries')
NOTE: The links to these Arduino libraries' zip packages are available at the FEX page https://www.mathworks.com/matlabcentral/fileexchange/72441-dht22-add-on-library-for-arduino
See Step 1-3 of 'To install the Adafruit Sensor library:' and 'To install the Adafruit DHT library:' on the same page. You will be required to rename the unzipped archives to 'Adafruit_Sensor' and 'DHT' before adding them to the libraries folder.
Once these are added to the libraries, you should be able to create the arduino object.
