Invent a santa detector. Catch him red-mitten handed when he takes a cookie from this spring-loaded cloud-connected plate.How it works:
A roller switch sits below a spring-loaded mechanism with a plate of cookies on top. When Santa takes a cookie from the plate, the the springs relax slightly and the roller switch releases, activating an LED and a cloudBit. When the cloudBit is activated, it triggers an IFTTT recipe to send you a text message [via IFTTT's SMS channel
] to let you know that Santa has arrived.
IFTTT (If This Then That) is a service that lets you connect to different web apps through simple conditional statements.
