why doesnt it work? i dont really know to work with arduino, i just found some code on the internet where you can take a picture by pressing the reset button. since i want the photos to be taken at a set interval, i dont really need to use the reset button, but i mostly kept the code the same, only moved the call of the path function for the sd card and the taking picture function. the problem is that the compiler gives me an error for ”fs::FS& fs’ and due to my lack, i dont understand what im doing wrong.

i tried looking up what to do in this case but no one has ran into the same problem, i tried different kinds of examples but nothing works
