We have tried different versions of IDE including 1.7.6 which is listed in instrcutables as well as the current version and others. Any guidance or insight would be welcome.
Arduino: 1.8.5 (Mac OS X), Board: "Arduino/Genuino Uno"
/Users/kenneth.j.faris/Documents/Arduino/sketch_mar04a/sketch_mar04a.ino:7:22: fatal error: TimerOne.h: No such file or directory #include <TimerOne.h>

compilation terminated.
exit status 1
Error compiling for board Arduino/Genuino Uno.
This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
I think all of the libraries necessary are in place. Thoughts?
