LIGHT-UP PLUSHLIGHT-UP PLUSH
Working With ProtoSnap
We’ll use the LilyPad pieces in the circuit to turn different LEDs on and off. Using
the E -Sewing ProtoSnap, we’ll examine how buttons and switches behave differently,
then snap the pieces apart and build them into a plush creature with light-up features.
Before we arrange our circuit on the felt, with the battery installed, slide the battery
holder switch to the ON position.
Buttons and switches are electronic components that control the flow of electricity
through a circuit. The circuit is closed when
current is allowed through by turning on a switch
or pressing a button. When a piece of the circuit is
disconnected by turning a switch or button off, it is
an open circuit.
