Hi all,
i'm trying to build a simple DC-Fan-Controller using an ATtiny85, as i want to keep the wiring as basic as possible.
My problem now, that i don't know, how to set the PWM frequency of the ATtiny to ~18-30KHz as this is the frequency, my fan supports.
There are many tutorials on the web, but as i have no idea, of what exactly i'm looking for, most of them are not very helpful...
I'm using the ATTinyCore.
What do i have to do, to get a PWM frequency in the range of 18-30KHz?
Any help greatly appreciated.
Thanks in advance!
