Check Your Understanding:
  1. 1. The Ultrasonic Rangefinder allows the robot to move until it is near an object, without actually touching it.
  2. True
    False
  3. 2. The Ultrasonic Rangefinder is:
  4. An Analog Sensor
    A Digital Sensor
    A Boolean Sensor
    A Character Sensor
  5. 3. What rules must you use when connecting the Ultrasonic Rangefinder?
  6. One set of wires is connected to an analog port and the other to a digital port
    Both sets of wires must be connected to analog ports
    Both sets of wires must be connected to consecutive analog ports with the INPUT wires plugged into the lower port number
    Both sets of wires must be connected to consecutive digital ports with the INPUT wires plugged into the lower port number
  7. 4. What equation does the Ultrasonic Rangefinder use to calculate distance?
  8. Distance = Speed * Time
    Distance = Speed / Time
    Distance = Speed * Time / 2
    Distance = Speed * 2 / Time
