Arduino nano iot33 fix sample rate?

@New-to-codin, your topic has been moved to a more suitable location on the forum. Installation and Troubleshooting is not for problems with (nor for advise on) your project :wink: See About the IDE 1.x category.

Please describe the problem; if you get errors during compile or upload, post them here (using code tags).

I'm not familiar with your board so can't be of much assistance.
