Just looking for the default Pin 9 PWM frequency (Arduino Duemilanove) Found lots of conflicting answers from 500hz to 32khz. And are any of the other PWM pins a different frequency.
and is there a min and max I can set them to if the default is not what I need.
From the Arduino reference for PWM write:
Writes an analog value (PWM wave) to a pin. Can be used to light a LED at varying brightnesses or drive a motor at various speeds. After a call to analogWrite(), the pin will generate a steady square wave of the specified duty cycle until the next call to analogWrite() (or a call to digitalRead() or digitalWrite() on the same pin). The frequency of the PWM signal is approximately 490 Hz.
