Sensors

R2026b
Read data from sensors connected to Arduino® hardware

Connect to different sensors to read data.

Use the Pin Explorer and Pin Configuration panes of the Arduino Explorer to interface with and visualize data from sensors both in MATLAB® and MATLAB Online™.

For a complete list of hardware supported in the installed version of MATLAB, see Supported Hardware. For more information regarding supported boards, workflows, and platforms supported on MATLAB Online, see Get Started with MATLAB Online for Arduino.

In the Pin Configuration panel, set the Mode and if required specify a Label to uniquely identify the pin. You can also use the plot panel of the app to interactively view data read from the Arduino board. For more information, see Use Arduino Explorer App.
