""" test_servo.py - Example for the Elegoo 4WD rover MicroPython library

	Show how to control the orientation of the ultrasonic sensor (using the Servo).

	Remark: the Rover class set the specific calibration data for the Servo
			included in the Eleego kit.
			You may need to adapt the calibration data when using another servo.
			See the rover.servo.calibration() call.
