What are Events?<\/h3>\n
In previous programs, you used a method called polling<\/strong> to access data from your button. This meant your program was continuously checking the state of the button (using a loop) to see if it had changed. Events<\/strong> allow you to sit back and wait for data to come to you! For example, in the program above, you simply subscribe to the State Change Event and wait for your function to be called when the button is pushed or released.<\/pee>[\/et_pb_code][\/et_pb_column_inner][\/et_pb_row_inner][et_pb_row_inner _builder_version=”4.4.5″ box_shadow_horizontal_tablet=”0px” box_shadow_vertical_tablet=”0px” box_shadow_blur_tablet=”40px” box_shadow_spread_tablet=”0px” module_id=”practice” module_class=”ph-hidden-anchor” vertical_offset_tablet=”0″ horizontal_offset_tablet=”0″ z_index_tablet=”0″][et_pb_column_inner type=”4_4″ saved_specialty_column_type=”2_3″ custom_padding__hover=”|||” custom_padding=”|||” saved_specialty_column_type=”2_3″][et_pb_code admin_label=”Practice – row hidden anchor” _builder_version=”4.4.5″ box_shadow_horizontal_tablet=”0px” box_shadow_vertical_tablet=”0px” box_shadow_blur_tablet=”40px” box_shadow_spread_tablet=”0px” vertical_offset_tablet=”0″ horizontal_offset_tablet=”0″ z_index_tablet=”0″ \/][\/et_pb_column_inner][\/et_pb_row_inner][et_pb_row_inner admin_label=”Row” _builder_version=”4.4.5″ box_shadow_horizontal_tablet=”0px” box_shadow_vertical_tablet=”0px” box_shadow_blur_tablet=”40px” box_shadow_spread_tablet=”0px” vertical_offset_tablet=”0″ horizontal_offset_tablet=”0″ z_index_tablet=”0″][et_pb_column_inner type=”4_4″ saved_specialty_column_type=”2_3″ custom_padding__hover=”|||” custom_padding=”|||” saved_specialty_column_type=”2_3″][et_pb_code admin_label=”Practice” _builder_version=”4.4.5″ box_shadow_horizontal_tablet=”0px” box_shadow_vertical_tablet=”0px” box_shadow_blur_tablet=”40px” box_shadow_spread_tablet=”0px” vertical_offset_tablet=”0″ horizontal_offset_tablet=”0″ z_index_tablet=”0″]<\/p>\n
Practice<\/h2>\n
<\/p>\n
        <\/p>\n
  1. Compare the code sample to the code sample in  Lesson 2<\/a>. Note the differences in the code and the program\u2019s output.<\/li>\n
        <\/p>\n
  2. Modify the loop to repeat every 10ms, 1000ms, 5000ms. Note how the behavior of your program changes (or doesn\u2019t) with the different times.<\/li>\n
    <\/p>\n
  3. Change the program output to print pressed and not pressed.<\/li>\n
    <\/p>\n
  4. Challenge: Add the green button and create an event for the green button.<\/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
      Still having issues?<\/strong><\/p>\n
