    ArduinoModules info : "KY-032 Infrared Obstacle Avoidance Sensor Module" より：
      The module has a pair of infrared LEDs, an emitter and a receiver.
      The emitting LED sends infrared light pulses at a certain frequency.
      When the light hits an obstacle is reflected back to the receiver LED.


    KY-032 Obstacle-detect module より：
      This sensor allows you to activate and deactivate the obstacle detection by manipulating the enable-pin ("EN").
      It is activated by default which means that the sensor is in detection mode by default.
      If you don't want that, you need to remove the jumper with the label "EN" and put a control signal on the enable-pin.
