this is ridiculous overkill. At this point it's time to use a 555 timer.

I tried the same thing a while back, but it doesn't work very well.
The whining you hear is from the fact the PWM frequency is in the audible range.
If you move the PWM frequency too high, the fan goes full on because the load on the motor is too low for PWM control to be effective.
Your best bet is trying to implement either a linear regulator, or use the AVR to control a buck converter.

LM317 and a digital pot might be a good solution.

that can do it with the computer an serial 9v

I did until i tried building an fm transmitter with one. lol I tell you they are terrible for high frequency stuff. Great for atmega8 prototyping stuff

ШИМ на мега8 не слишком жирно? или просто другого контроллера не было?

@Manucayn да он нуб просто =) я таким тоже по первости страдал правда я всегда писал на асме... баском это уж совсем изъёбство

@Manucayn он нуб просто, я такой хернёй по первости тоже страдал только писал всегда на асме =)

з. ы. да ещё судя по противному звуку у него Low freq PWM а это жопа
hmm just pwm? no feedback from tach?
I want to se RPM and such..
Dont use a powerful avr to do the same thing any transistor could do.. ..

Well done NOT
We're making a M&M Sorter and Counter
Also programmed with Bascom
Stay tuned for movies of it!!

To piszczenie z PWM jest? Jeżeli tak to maż zbyt mała częstotliwość:) Ps. jaki tranzystor jest do kluczowaniu użyty?

Mam tą książkę dobra jest, fajnie działa PWM.
Zobacz moje boje z M8. POZDRAWIAM

Hi! What is the output voltage of PWM?

Polecam książkę "Programowanie mikrokontrolerów AVR w języku BASCOM" Marcina Wiązania. Tam jest podany przykład który tutaj prezentuje.
