Thanks for the video. I was specifically wondering if 3.3 volts from an ESP or a Raspi Pico could control the pwm signal of the a 12v fan. That spec that you have a link for doesn't list the minimum voltage for a logical high on the PWM signal. Other specs I've seen showed the max voltage for logical low was on the order of 0.8v so I figured 3.3v signal would work, but your video proved that it does. Thanks!

thanks for the video. i have been trying to drive led using pwm from multiple esp32. first few hours they are in sync, unfortunately after 4 hours or so, the pwm start to run out of sync. wonder if you have encountered such issues.

It would be nice if you could upload the code somewhere. :) nice project!

Any reason you chose interrupts vs using PCNT channel?

after all that, why didn't you share the code? @Neils

Thanks - great intro into how to do this. Couple of questions on what software/hardware you're using? I.e the bench supply, the scope hardware/software? Always keen to get recommendations on this. Side note - minor pronunciation thing is 'W' is pronounced "double u", otherwise is sounds like PVM. This was a major pain when websites used to be prepended "www"!

Hi Marcos, thank you for your comment! You are absolutely right about the pronunciation :). I'm using a Hantek 6022BE (very cheap digital oscilioscope).
