## Verhalten

A probe is an element that simply displays the value at a given point in a circuit. It does not itself interact with other components.

In most respects, the probe component duplicates the functionality found in a Pin component configured as an output pin. The primary difference is that if the circuit is used as a subcircuit component, then an output pin will be a part of that interface, whereas a probe is not. They also are different in that the probe does not have a Data Bits attribute to be configured: The bit width is inferred from whatever value it happens to see on its input. Graphically, they are similar but have slightly different borders: A pin has a thick, black border, whereas a probe has a thin, gray border.

## Pins

A probe component has only one pin, which will acts as an input to the probe. The width that this pin accepts is adaptive: The probe will adapt to inputs of any width.

## Attribute

When the component is selected or being added, the arrow keys alter its Facing attribute.

Ausrichtung
  The side of the component where its input pin should be.
Label
  The text within the label associated with the component.
Label Location
  The location of the label relative to the component.
Label Font
  The font with which to render the label.
Radix
  The base (for example, binary, decimal, or hexadecimal) in which a value is displayed.

## Verhalten des Schaltwerkzeugs

Keines.

## Verhalten des Textwerkzeugs

Allows the label associated with the component to be edited.
