Max. frequency output from arduino

[Anonymous]

Hi there,

I'm building the project variable frequency generator using arduino (arduino
pro mini) mentioned in your website. I have used the same components to build
the entire project as mentioned in this website. I have a question. What is
the maximum frequency that an arduino pin can give as an output. In the
official site, I have seen that , tone() function can output a maximum
frequency of roughly 65kHz. Is there any way by which I can output higher
frequencies ?

The maximum output frequency is based on the clock we are using with Arduino. As u told 65KHz is the maximum for Arduino UNO, pro mini etc. The only way i found is to go for higher end Arduino for higher frequencies.
