Since a couple of days, I have been having troubles with compiling sketchs and choosing a port for arduino uno (I annexed a picture). I´m not so sure if I´m doing it right. I have been on this website for a few period of time.
Everytime I try to save or verify the code it appears a message "Compilation failed. please report this issue on our forum"
I would really appreciate a quick reply or explanation, because I must deliver this for saturday. I hope somebody could help me.
