When should I use Attach\/Detach events?<\/h3>\n
These events are useful if you need to attach and detach Phidgets while your program is running, disable or enable program features, or monitor the connection to your Phidgets. For example, if you made a video game that used Phidgets as input (something like this<\/a>), you would want to know if a device got disconnected so you could pause your game!<\/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. Run the code sample. Disconnect and reconnect your USB cable while the code is running. Note what happens.<\/li>\n
    <\/p>\n
  2. All Phidgets have Attach and Detach Events. Modify your code to add an LED and Button. Add an Attach and Detach Events for the LED and button. In each Attach Event, print \u201cAttach\u201d plus the component that is attached. For each Detach Event, print \u201cDetach\u201d plus the component.<\/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
