Obj1 = instrfind('Type', 'serial', 'Port', 'COM19', 'Tag', '') Īnd this is the serial event of arduino bool gotalfa = false ĭo I have to change anything in my matlab/arduino code. This is my matlab code, val_a = matt(n,:) Disclaimer: The tutorial is not a replacement for reading the Matlab Documentation on Serial Interfacing nor does it conver all the concepts and implementation details of serial communication and the RS-232 protocol.

However in the serial monitor, I can not read any value coming from matlab. Objective: This tutorial teaches you how to use Matlab serial objects to interact with external hardware. My plan is to convert this two numbers in to a string and send to the arduino. As mentioned in the introduction part there is a serial communication between arduino and Matlab. BLOCK DIAGRAM OF THE SYSTEM In figure 1 two devices are shown, the first one is the computer and the second one is Arduino microcontroller (In the blue one). I use the default Serial port of Arduino this time to connect with the. 1: communication between Matlab and Arduino 4 II. I am trying to send some data from Matlab to arduino. The MATLAB function reads the analog voltage from a REES52 Heart Rate sensor.
