/*  04.020 - Grove analog light sensor

   This sketch demonstrates how to use the Grove analog light sensor.

   The analog light sensor  is an analog device. It outputs a voltage
   level that depends on the intensity of ambient light.

   Upload this sketch and start the Serial monitor (you can also use
   the serial plotter). Wave your hand over the sensor and notice the
   change in the output displayed in the monitor.


   Components
   ----------

    - Grove Base Shield
    - An Arduino Uno compatible board (such as Arduino/Genuino Uno or Seeeduino)
    - Grove analog light sensor
    - One Grove cable

    IDE
    ---

    Arduino IDE

    Libraries
    ---------

    -

    Connections
    -----------

    Use a Grove cable to connect the light sensor module to Base Shield connector A0.
