Infinitum is an Arduino-powered light table that turns on when items are placed on it, but turns off when they are removed. This infinity table is designed for people who never tidy up and who leave their belongings everywhere. When objects are placed on the table, it lights up—providing a beautiful backdrop for the artifacts with an illusion of infinite depth. Users are encouraged to tidy up before they leave a room, since the light table will only switch off once everything is removed from its surface.
The table construction includes a piezo sensor switch which, when activated, lights up the LEDs. (The piezo sensor converts vibration to voltage, or voltage to vibration, meaning that makers can use the device as a buzzer for making beeps, tones and alerts, or as a sensor to detect fast movements like knocks.) In simple terms, the vibration of an object being set on the table triggers the piezo sensor. Once the piezo is set off, the NeoPixel Digital RGB LED strip turns on white lights. The piezo, as well as the LEDs, are both connected to an Arduino board hidden under the surface, accessible through the underside of the table.
