As a project i want to make a device, which controlles my computer fans.
The fans i use arn't PWM fans, but that doesnt really matter, for u can PWM them anyways
Since the Arduino Uno i got 5V outputs, I added a circuit with some MOSFETs (BUZ11) to get them up to 12V. PWM-ing them works like a charm (if the PWM-frequency is increased; it kills the buzz).
Now i want to read out the PWM-percentages. Can i just use fprintf() in the arduino software? Or do i have to work around that, witch will be a pain in the a**
In the future i also planned on reading out temps(either LM35s or a voltage-deviding NTC), but that's for the future
Help will much be appreciated,
