The building is straightforward, the LED will light up accordingly to the output signal.

Since I'm using a PWM output, depending on the board application, a passive low pass filter can be customized by choosing the values for R and C components, i.e. a 1K resistor and a 100nF capacitor will lead to a cutoff frequency of 1591.54Hz.


You can’t perform that action at this time.
