How to get 20khz PWM on pin D9

Pin D9 is the output from the Timer/Counter 1 Output Compare Register A (ORC1A). The highest speed you can run it at is 16 million steps per second or 62.5 kHz for 9-bit PWM (16 MHz / 256 steps). The way to get 20 kHz is to have the timer reset at 800 (16,000,000 / 20,000) instead of 256. This give you a PWM range from 0 to 799.

What is PWM and how does it work?

The third type of fans that use four wires are PWM fans and that is what will be discussed in this article, along with PWM pumps. PWM (Pulse Width Modulation) or modulation with the width of an impulse, is a widespread term in the world of electrical engineering. It has a broad range of application, like in the field of telecommunications ...

Pulse Width Modulation

The pulse width modulation technique is used in telecommunication for encoding purposes. The PWM helps in voltage regulation and therefore is used to control the speed of motors. The PWM technique controls the fan inside a CPU of the computer, thereby successfully dissipating the heat. PWM is used in Audio/Video Amplifiers.
