can you give me news? now it's working? I have the same problem

Thanks

I use arduinoIDE 2.3.3

Hi, I found my problem : not the same ground between fan and esp32. now it's working good!

Hi,

thanks for your answer.But for the moment  it's not working (is the same with all digital pin D2/D9 and all). I don't see why! the mofset working good but normally, when pwm>30 fan must turn slowly, and it turn fast.

for example : 

#define fanChannel 0             

#define fanResolution 8   

#define fanFrequency 10000   

#define fanPin 2                           //D9  

int pwm = 0;

void setup(){

Serial.begin(921600);

ledcSetup(fanChannel, fanFrequency, fanResolution);

ledcAttachPin(fanPin, fanChannel);

pinMode(12,OUTPUT);   // fan power with mofset on the pin12

digitalWrite(12, LOW);

}

void loop(){

digitalWrite(12, HIGH);

for(pwm = 0; pwm <= 255; pwm++){  

Serial.println(pwm);

 ledcWrite(fanChannel, pwm);

 delay(250);

  }

 digitalWrite(12, LOW);

 delay(5000);

}

I tested with 2 fans : noctua NF-A12x15pwm and NF-P14r redux-1500pwm
