What Does Closing My Phidget Do?<\/h3>\n
Closing your Phidget breaks the connection between your code and your physical device. This means that after calling close, your object can no longer be used in your code. Closing will also cause the device to return to its default state. For example, if you were powering an LED, the LED would turn off after closing, or, if you were controlling a motor, the motor would stop spinning after calling close.<\/pee>[\/et_pb_code][et_pb_code admin_label=”When should I close my Phidget?” _builder_version=”4.6.6″ 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
