# First, you will need to locate the Arduino IDE’s Servo library, and find the file inside it named ServoTimers.h. For the 1.6.x versions of the IDE, this file can be found in libraries/Servo/src/avr/ServoTimers.h. If you are using Mac OS X, you will need to right-click on the Arduino IDE icon and select “Show Package Contents” to see the files inside.
