Matlab close arduino connection. This example shows how to enable callbacks to read streaming ASCII terminated data from an Arduino® board using the serialport interface. Feb 22, 2026 · 1. I was . It keeps saying that the connection to arduino is existing eventhough I use "clearvars -global a". This MATLAB function finds existing persistent serial port connections and returns an array of serialport objects corresponding to each connection. The Arduino code initializes serial communication and sends the number 3, while the MATLAB code attempts to read this value.
