Get started using MATLAB^® Support Package for Arduino^® Hardware. In this video, we explore the basic functions for controlling digital and analog inputs and outputs on your Arduino device directly from MATLAB. We read inputs to the Arduino from a button and a potentiometer. We also use the Arduino to write digital and PWM signals to an LED. Finally, we see how you can play a tone on a piezo speaker. Each of these tasks is done at the MATLAB command line and then again from an interactive UI built in MATLAB.
