The switch here uses 5V power using the Adafruit Circuit
playground limiting the voltage coming from a mini-USB cable. The “switch” consists
of two shoes with foil wrapped around the heels. When the heels touch, they
LEDs on the shoes light up. This device provides excellent feedback for all
those people who feel stuck in the world of Oz, or any other realm that can be
exited via clicking heels. To encourage safety and the longevity of the product,
we have limited the lights by adding a 100 Ohm resistor to prevent the lights
from glowing too brightly and burning out.
After all, who knows when someone’s friend is prone to burning?
Note: Product may put user at increased risk of flying monkey attacks.
