- * This is a driver for the USB PhidgetServo version 2.0 and 3.0 servo
- * controllers available at: http://www.phidgets.com/
- *
- * Note that the driver takes input as: degrees.minutes
- *
- * CAUTION: Generally you should use 0 < degrees < 180 as anything else
- * is probably beyond the range of your servo and may damage it.
