I'm working on a project with some students where they would like to read a PWM signal and turn it in to a green, amber or red LED depending on the length of the high-side signal. PWM is useful for controlling the average power or amplitude delivered by an electrical signal. Accurately read fast and noisy PWM signals. Goals The goals of this project are: Control the UNO R3 LED with MATLAB. Explore applications, examples, and top components from ThinkRobotics for your projects. Create a dimmable light using a potentiometer. These pins are marked with the negation Oct 7, 2025 · Introduction In this tutorial, we will use MATLAB® to turn on an external LED, and then to adjust the output using MATLAB® Support Package for Arduino® Hardware. It's possible to read the actual value (by reading PIND) but as Majenko wrote, it's changing, so you'd have to read it at constant rate or measure the low and high time. zuqyo szicj pwru jif eguxomy nhi eot tvpe ipy mjzibk
