Pulse Width Modulation

PreviousInfraredNextMicrosystems Technologies

Last updated 7 years ago

Pulse width modulation (PWM) is a fancy term for describing a type of digital signal. Pulse width modulation is used in a variety of applications including sophisticated control circuitry. A common way we use them here at SparkFun is to control dimming of RGB LEDs or to control the direction of a servo motor
