  1. Change your Duty Cycle value to 0, 0.5, and 1. Note what happens to your LED with each value.<\/li>\n
        <\/p>\n
  2. Modify your program so the brightness of your LED slowly increases and decreases before turning off. Hint: Use a loop. <\/li>\n

          1. Make sure the USB cable from your VINT Hub to your computer is attached properly.<\/li>\n
          2. Make the Phidget cable (the black, red and white one) is connected to your VINT Hub and to your Humidity Phidget properly).<\/li>\n
          3. Make sure no other program is running that uses Phidgets. If a Phidget is already in use in another program, it will be busy and won’t respond to this one.<\/li>\n<\/ol>\n
