GLOSSARY
Sew Tab – Silver-rimmed holes on LilyPad pieces where conductive thread
can be connected, sometimes called petals or pins. The silver around the hole
connects to the electrical components built into each LilyPad piece.
Short Circuit (“short”) – A direct, often accidental connection
between power (+) and ground (–) of a power source. Electricity will flow
quickly from power to ground, bypassing the rest of your circuit. A short
between power and ground will drain the battery very quickly. Double check
to make sure loose threads are not accidentally touching another part of
your circuit.
Switch – An electronic component that controls how electric current flows
by connecting or disconnecting its two sides. A switch turned to the ON position
closes (completes) the circuit, allowing electricity to flow and, when turned OFF,
opens or disconnects/interrupts current flow. A switch can be momentary –
only connecting the two sides when held or pressed – or maintained, meaning
the two sides are connected until the switch is moved to a different position.
Switches are not polarized; either end can be connected to positive or negative.
Trace – A pathway for electric current to flow through, made of a conductive
material such as metal. The projects in this guide use conductive thread to
create traces. On LilyPad ProtoSnap boards, the silver lines on the printed circuit
boards are also traces.
