Hello,
Im trying to upload a sketch to my arduino nano. But I have this error:
avrdude: ser_open(): can't set com-state for "\.\COM9"

Does somebody know what that means?

@parachutesj Thank you so much, I will check it out.

Hello!!
I'm new in the sensor world, I've already done some basic movement sensors, but what I really need is a dimensional sensor than can take measurements, is that possible to build with the info in this page?
Thanks
