Determine Who’s In the Office with a Quick Glance at Whooooo’s In
From Craig Walker on Hackster.io:
Whooooo’s In is a prototype of the interactions between humans and their devices. It makes use of WiFi, laser cutting and open source code.
Whooooo’s In tracks the presence of people in the workspace by constantly listening for WiFi signals identified by the MAC address. One MAC address is represented by one servo. When present, the servo (attached to a disc) rotates opening the eye to reveal the colours behind.
