So, no chance to control more than 2 pwm fan by arduino uno mega? dlloyd december 12, 2016, 10:20pm 11. on an uno: with timer2, could get dual pwm at 31.37khz using mode 1. using mode 5 only get one pwm at 25khz. so, using timer 1 and timer 2, could get 4 pwm, 2 at 25khz and 2 at 31.37khz. or 3 pwm at 25khz.
25 Khz 4 Pin pwm fan control With arduino Uno Hackster Io
25 Khz 4 Pin Pwm Fan Control With Arduino Uno Hackster Io Hello, i've been trying to control a 4 pin computer fan using the arduino. these fans take a pwm signal on their 4th pin to control the speed of the fan, from the spec's of the fan it says it requires expects: the following requirements are measured at the pwm (control) pin of the fan cable connector: pwm frequency: target frequency 25 khz, acceptable operational range 21 khz to 28 khz maximum. This is the pinout of a standard pwm fan: black: ground. yellow: 5v, 12v or 24v (depends on fan model, usually 12v for desktops, 5v for laptops) green: sense. used to measure rpm. blue: pwm control signal at 5v, 25khz. notice the presence of a notch on the connector: this is to ensure that you don't connect it backwards, and also to ensure. I have been wondering about this project and how to control my 4 pin pwm fans. i had 5 laying around and thought mine as well give it a shot. the frequency values can be adjusted between 125 hz 8 mhz as well as a variable duty cycle. the circuit utilizes the mode 10 pwm phase correct on timer 1 ocr1a (pin 9) and icr1 (pin 10). Fans don't use stock pwm frequencies. the pwm control frequency needs to be 25khz. a 16mhz arduino can do this relatively easily through software. just search "4 wire fan arduino" and there's quite a few posts on it, including sample code to set the prescaler frequency so the output pwm is at 25khz.

Using arduino motors, mechanics, power and cnc. good day, i am using a arduino nano and i have a code to control the speed of a pwm 4 wire fan via a potentiometer and a pwm of 25 khz, the potentiometer increase or decreases the duty cycle from 0% to 100%. the code works fine but i want to control 2x of the same fans each with its own. Add a comment. you can configure timer 1 to cycle at 25 khz in phase correct pwm mode, and use it's two outputs on pins 9 and 10 like so: pwm output @ 25 khz, only on pins 9 and 10. output value should be between 0 and 320, inclusive. void analogwrite25k(int pin, int value) {. switch (pin) {.
