The plain-English version
A signal technique that varies the portion of each cycle spent in one state.
Why it matters
It can control suitable hardware through a documented switching pattern.
Let’s make it click
An indicator's apparent brightness is varied using a supported PWM output.
Vibe Bro’s heads-up
PWM is not universally a smooth analog voltage; behavior depends on the pin, board, connected device, and any filtering circuitry.

Supported: PWM varies duty cycle and is not universally a smooth analog voltage; board, filtering, and load matter.
