Pulse Width Modulation (PWM) Basics: How PWM Works

Due to the fact that the interval between pulses is so brief, the LED doesn’t actually turn off. In other words, the LED’s power source switches on and off so fast (thousands of times per second) that the LED actually stays on without flickering. This is called PWM dimming, and such as circuit is just called a PWM LED dimmer circuit.

Analog Output through PWM | How to control …

PWM or Pulse Width Modulation is a technique for getting an analog output using digital signals. A digital signal, in general, can have either of the two values: HIGH/ON or LOW/OFF . If we switch the signal between these two values at an extremely fast rate, say, 500 times in 1 second, the signal at the output will appear to be continuous; it will seem as if it is an analog signal.
