[PD] OT: PWM frequency of Arduino

[Derek Holzer]

Hi all,

using Pduino as a CV generator for my modular. First problem is to make 
a low pass filter circuit to remove the PWM noise and get smooth DC out. 
Might be helpful to know the default PWM frequency. I know it's set in 
the firmware, but I've read everything from 450 Hz to 32 Khz, and 
several other numbers in between out there in Googleland. I'm using 
Arduino 0011 and the Arduino NG board (ATMega8 controller). Anyone have 
the definitive answer?

best!
d.
