Default PWM Rate

Other Hardware LEDs and Multiplexing
1

Hello everyone!

I have an Arduino Uno I am using to light up some LEDs. Could anyone tell me, out of the box, what is the default PWM rate (Hz) on the output pins? I found this post http://arduino.cc/forum/index.php/topic,117425.0.html but frankly it is over my head (for now...)!

Thanks

...The frequency of the PWM signal is approximately 490 Hz. ...

Thanks! read the manual I guess...

what is the default PWM rate (Hz) on the output pins?

The timers are configured with a prescaler of 64:1, 16Mhz / 64 / 2 = 488hz.

488hz.
