Add #include <Wire.h> in the code
Edit the <Wire/Wire.H> inside the PCA9685.h file to <Wire.h> with e.g. "Notepad++" (!not windows notepad!)
Or replace the PCA9685.h file with the one attached.
Works with IDE 1.6.1
The Adafruit library should work for servos and LEDs.
Don't know. Happy with this one.
