I'm not at home (holiday location..)
so it's all from memory.
There are 2 types of Nanos. Both types needs a setting for uploading to work at all.
pico_2_heavy_filter_bv WILL compile when you choose
board: Arduino Nano
Uploading is dependent on which type of Nano you have.
from the menu,
processor: ATMega328
or
processor: ATMega328 (old bootloader)
It can be a pain to work out which one you need to use
but once you know, it's reliable and easy
a trap:
if there are two copies of the .ino file in the directory
and you double click to load one of them
you will find it will not compile.
Delete the extra file and try again.
The Arduino IDE needs the .ino file to be inside a directory named the same.
eg:
a folder named "pico_2_heavy_filter_bv" is to contain a file named
"pico_2_heavy_filter_bv.ino"
