A: SCFM, which stands for standard cubic feet per minute, is a numerical rating that shows the quantity of air flow a pneumatic tool requires to function at peak performance. The actual value varies based on the pressure exerted by the air in the compressor, which is typically measured in pounds per inch.
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.
