What is PWM and Why Does Frequency Matter? Pulse Width Modulation, or PWM, is a clever technique microcontrollers like the Arduino use to simulate an analog output using a digital signal. If you turn it on for a longer duration than you turn it off, the light appears brighter. On D0-D5 it changes the shared PWM20 frequency, and on D6-D15 it changes the default software-PWM period. PWM On XIAO nRF54L15 analogWrite() PWM is available on D0-D15. Think of it like this: you’re rapidly turning a light switch on and off.
