We created an ambient device that senses when people enter and exit a room and displays that information visually. It uses an infrared motion sensor and neopixel lighting. Whenever the IR sensor detects a person walking past it, a count goes up which is mapped to the neopixel lighting. Every time the count goes up by two, i.e, a person enters and leaves the room, one light out of sixteen turns on. As the count continues to increase, the amount of lights on increase and the color of all of the light goes from green to red. A button can be pushed to reset the count. The setting in which this device would work is a room with only one entrance. It counts the amount of people by a person going in and out.
