when your coin slot is exposed, this wearable hip-pack vibrates that area to make you aware of it. you decide to cover up, or let it all hang out.
the coin slot detector is a simple way to tackle the complicated modern problem low-rise jeans can cause. with this hip pack, now your coin slot itself is given the sensory power to alert you as to when it's exposed. both you and your coin slot decide what's next.
tech summary: using a Lilypad Arduino, vibrating motor, and a photoresistor (measures the amount of light in your coin slot), you will make a wearable apparatus. when the photoresistor/your coin slot is covered, the hip-pack is at rest, when it/your coin slot is exposed, this triggers the vibrating motor to start vibrating & let the user know.
Step 1: Ingredients
for this project you'll need:
-11.5 x 14.5 in fabric
-photoresistor (sometimes called photo cell)
-1.5 to 5 V step-up battery pack
for protoyping (not pictured):
-breadboard (you can buy this at Radio Shack)
-alligator clips (also buy these at Radio Shack)
-USB to Serial Converter
