My team IoT Smackdown created the 'Click-o-Matic,' an internet-enabled instant voting meter. Users across the world could log on to a website and click as fast as they can on either 'A' or 'B' to move a real-world display needle to the left or right. When the needle went all the way to one side, an LED would display a series of either blue or green lights to indicate the that the voting was over and the winner had been chosen.
We used the Electric Imp with LED lights and a servo motor for the hardware. We used the PubNub API to sync data to and from the Electric Imp and across each web site instance.
