Understanding Your Circuit:
LilyPad Button
The LilyPad Button Board is also a type of switch. When you press the
button in the middle of the board, it connects the two sew tabs and allows
current to flow through. When you let go of the button, the connection is
opened again, and the button springs back into place. This button is an
example of a momentary switch – it is only active when an action is applied.
This is slightly different from the slide switch, which is an example of a
maintained switch, meaning its state remains the same until changed.
Try pressing
the button on
the ProtoSnap
to see how it
controls the
LED.
