Hello from Gregg C Levine
PWM - Pulse Width Modulation. It's used for DC motor drive systems.
That includes servomechanisms. Some power supplies use it as well.
Before we get into a semi-on-topic discussion here, as this only
partly applies to the Stamps, I suggest you check this subject out via
your public library.
