Servo

javadoc

The Servo service is used to control servos through a micro-controller such as an Arduino.  First an Arduino will need to be loaded with an appropriate PDE (such as ArduinoSerialBare.PDE).  An Arduino service will need to be started and configured to communicate with the Arduino micro-controller. 

A servo can be connected to the Arduino micro-controller.  If the servo is connected to pin 9 then a Servo service can be started and attached to the Arduino service and pin 9.
