When I go to write a program or use a library, all except for one does not work. When I try to include the files using #include <file.h>
it does not work except for the Wire library. I have tried to replicate the same circumstances from that of the Wire library, yet the libraries still do not work. In the Arduino compiler, when I type it in, it also does not change the color to orange as it should when you include an acknowledged library. I have tried a lot of things, and I know the problem, it's just that I don't know how to fix it; any ideas? It would be greatly appreciated, and I have also posted pictures to hopefully help you out to visualize it.
Thank you
