What is the name of the Arduino library need to be included in your command to control servo motors?

How does a PING ultrasonic distance sensor works?

• by transmitting an ultrasonic burst and providing an output pulse that correspond to the time and echo return to sensor

• by providing variable voltage as an output that correspond to time values to echo return sensor

• by transmitting an ultrasonic light and providing digital output pulse that correspond to the echo of time return to sensor

• by providing burst analog signal output pulse that correspond to the time and echo return to sensor
